Step 1:I'll solve this problem step by step, demonstrating how to manipulate these nested radical expressions.
Example 1: Squaring a Cubed Root $$(\sqrt[3]{x})^{2}
Step 2:: Understand the expression
- We have a cubed root of x, which is then squared - This means we're taking the cube root of x and then squaring the result
Step 3:: Simplify the expression using exponent rules
- So, $$(\sqrt[3]{x})^{2} = (x^{\frac{1}{3}})^{2}
- Squaring means raising to the power of 2
Step 4:: Apply exponent multiplication rule
Example 2: Cubing a Square Root $$(\sqrt{x})^{3}
- When raising a power to another power, multiply the exponents
Step 5:: Understand the expression
- We have a square root of x, which is then cubed - This means we're taking the square root of x and then cubing the result
Step 6:: Simplify the expression using exponent rules
- So, $$(\sqrt{x})^{3} = (x^{\frac{1}{2}})^{3}
- Cubing means raising to the power of 3
Step 7:: Apply exponent multiplication rule
- $$(\sqrt{x})^{3} = x^{\frac{1}{2} \times 3} = x^{\frac{3}{2}}
- When raising a power to another power, multiply the exponents
Final Answer
1. (\sqrt[3]{x})^{2} = x^{\frac{2}{3}} 2. (\sqrt{x})^{3} = x^{\frac{3}{2}} Key Insights: - When squaring a cubed root, the exponent becomes \frac{2}{3} - When cubing a square root, the exponent becomes \frac{3}{2} - The general rule is to multiply the original fractional exponent by the new power
