In the realm of mathematics, a journey through numbers and operations unveils a world of intricate patterns and precise calculations. This article embarks on such a journey, aiming to demystify the process of calculating the expression 3_3^2 ÷ 5/6. This seemingly complex expression involves a combination of exponents, mixed numbers, and division, but with a step-by-step approach and a clear understanding of mathematical principles, we can break it down into manageable parts and arrive at the answer in its simplest form. Whether you're a student seeking to enhance your math skills or simply a curious mind eager to explore the world of numbers, this article will serve as your guide.
Understanding the Expression
Before diving into the calculations, let's dissect the expression 3_3^2 ÷ 5/6 and understand its components. The expression involves a mixed number, an exponent, and a fraction, all connected by the division operation. A mixed number, in this case, 3_3, combines a whole number (3) with a fraction (3). The exponent, denoted by the superscript 2, signifies that the base number is multiplied by itself. Finally, the fraction 5/6 represents a part of a whole. To solve this expression, we need to address each component systematically and follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Step 1: Converting the Mixed Number
The first step in simplifying the expression is to convert the mixed number, 3_3, into an improper fraction. An improper fraction has a numerator that is greater than or equal to its denominator. To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction and add the numerator. The result becomes the new numerator, and the denominator remains the same. In this case, we have 3_3. Assuming the fractional part is meant to be 1/3, we multiply the whole number 3 by the denominator 3, which gives us 9. Then, we add the numerator 1, resulting in 10. So, the improper fraction equivalent of the mixed number 3_1/3 is 10/3. It's crucial to accurately convert mixed numbers to improper fractions, as this conversion lays the foundation for the subsequent calculations.
Step 2: Evaluating the Exponent
Now that we've converted the mixed number to an improper fraction, the next step is to address the exponent. The expression 3^2 indicates that the base number, which is now 10/3, is raised to the power of 2. This means we need to multiply the fraction by itself. So, (10/3)^2 is equivalent to (10/3) * (10/3). To multiply fractions, we multiply the numerators together and the denominators together. In this case, 10 * 10 = 100 and 3 * 3 = 9. Therefore, (10/3)^2 equals 100/9. Understanding exponents and how they apply to fractions is essential for accurate mathematical calculations.
Step 3: Dividing by the Fraction
The final step in solving the expression is to divide the result from Step 2 by the fraction 5/6. Dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of a fraction is obtained by swapping its numerator and denominator. So, the reciprocal of 5/6 is 6/5. Now, we can rewrite the division problem as a multiplication problem: (100/9) ÷ (5/6) becomes (100/9) * (6/5). To multiply fractions, we multiply the numerators together and the denominators together. However, before we multiply, we can simplify the fractions by looking for common factors between the numerators and denominators. 100 and 5 share a common factor of 5, and 9 and 6 share a common factor of 3. Dividing 100 by 5 gives us 20, and dividing 5 by 5 gives us 1. Dividing 6 by 3 gives us 2, and dividing 9 by 3 gives us 3. Now, our multiplication problem is simplified to (20/3) * (2/1). Multiplying the numerators, 20 * 2 = 40, and multiplying the denominators, 3 * 1 = 3, we get the fraction 40/3. This fraction represents the final answer to the expression.
Step 4: Expressing the Answer in Simplest Form
While 40/3 is a valid answer, it's not in its simplest form. To express a fraction in its simplest form, we need to ensure that the numerator and denominator have no common factors other than 1. In this case, 40 and 3 have no common factors other than 1, so the fraction is already in its simplest form. However, 40/3 is an improper fraction, meaning the numerator is greater than the denominator. It's often preferable to express improper fractions as mixed numbers. To convert an improper fraction to a mixed number, we divide the numerator by the denominator. The quotient becomes the whole number part of the mixed number, the remainder becomes the numerator of the fractional part, and the denominator remains the same. Dividing 40 by 3, we get a quotient of 13 and a remainder of 1. Therefore, the mixed number equivalent of 40/3 is 13 1/3. This is the simplest form of the answer, representing the final result of our calculations.
Alternative Interpretation and Calculation
It's worth noting that the original expression, 3_3^2 ÷ 5/6, could have an alternative interpretation. If the intention was to calculate 3(32) ÷ 5/6, the solution would be different. In this case, we would first evaluate the exponent in the exponent, which is 3^2 = 9. Then, we would calculate 3^9, which equals 19683. Finally, we would divide 19683 by 5/6, which is the same as multiplying 19683 by 6/5. This gives us 118098/5, which can be expressed as the mixed number 23619 3/5. This alternative interpretation highlights the importance of clear notation and understanding the order of operations in mathematical expressions.
Conclusion
Calculating the expression 3_3^2 ÷ 5/6 has been a journey through the world of mathematical operations. We've explored mixed numbers, exponents, fractions, and the crucial process of division.
