# Math Help - Radicals Help

1. ## Radicals Help

Please help me solve this problem. I have an exam coming up next friday and I'm kind of stuck with these type of problems.

Description on how to solve this would be much appreciated.

2. ## Re: Radicals Help

hi grande punto

that is not an equation,so you can't really solve it!

if you want to simplify it then:
$\sqrt[4]{x^4+x^2+\frac{1}{4}}=\sqrt[4]{(x^2+\frac{1}{2})^2}=\sqrt{x^2+\frac{1}{2}}$

3. ## Re: Radicals Help

thanks very much for the response. sorry my english in not very good because i study in italian. i meant simplify.

can u please help me understand this. when you simplify, shouldn't it be 4√  (x^2 + 1 + 1/2)^2 how did u get rid of the 1?

4. ## Re: Radicals Help

try expanding (x^2 + 1/2)^2,and then try expanding (x^2 +1+1/2)^2=(x^2 + 3/2)^2. See what you get.

Also i didn't realise that you had a in your radical and not x.sorry about that!
