No
Adding variables with like bases doesn't allow you to add their exponents. If the last expression was X×X½ then it would be true.

$ \sqrt[2]{x^{3}} = \sqrt[2]{x^{2}\cdot x} = \sqrt[2]{x^{2}} \cdot \sqrt[2]{x} = x \sqrt{x} $

Okay. Thanks. I was thinking it had to be x * x^(1/2).

Do these mean, "The square root of x is cubed." Are these the same, but just written in different form? I am guessing that the one on the left is the way to use less parenthesis.

This is the correction. Is it true now? I am thinking x^(2/2) • x^( 1/2) = x^(1/2) • x^(1/2) • x^(1/2)

$\displaystyle \sqrt[2]{10^{3}}=100 \\ \left ( \sqrt[2]{10} \right )^{3}\approx 31.62 $

sqrt(1000) ? 31.62, not 100
