## anonymous 5 years ago square root of 16x^6...seems simple, but do i have to work it all out or is there a trick with the exponents?

1. anonymous

there is a trick. The nth root is the same as raising to the power of 1/n

2. anonymous

$\sqrt[a]b = (b)^\frac{1}{a}$

3. anonymous

so 16x^3?

4. anonymous

no, you have to apply the power to the 16 as well

5. anonymous

so 4x^3

6. anonymous

indeed.

thanks
