## qwertyfreak Group Title Which of the following represents the radical in simplest form? √x^16 2 years ago 2 years ago

1. Kreshnik

if you'd have $\LARGE \sqrt{x^2}$ how would it be? :)

2. qwertyfreak

huh?

3. johnrr

x^16 = ( x^8 )^2 This might help?

4. qwertyfreak

x^8 x^4 x^7√x The question was which of the following, and I forgot to list the following. So here..

5. Kreshnik

yes but you need to know this formula: $\Huge \sqrt[a]{x^b}=\left(x\right)^{\frac ba }$ now you have: $\Huge \sqrt[2]{x^{16}}=x^?$ how would it be?? (just follow the formula)

6. Kreshnik

@qwertyfreak still confused? :)

7. qwertyfreak

uh yeah..

8. Kreshnik

where are you confused

9. qwertyfreak

everywhere, I dont know how to do this

10. Kreshnik

$\Huge \sqrt[2]{x^{16}}=\left(x\right)^{\frac{16}{2}}=x^?$
