Question

Simplify each expression as much as possible, and rationalize denominators when applicable. √4/X^4=?

Answer 1

`\sqrt{(4)/(x^(4) ) }= 2x^(-2)`

Explanation:

We have

`\sqrt{(4)/(x^(4) )}` this equals to

`\sqrt{(2^(2) )/(x^(4) )` now we are going to cancel the squares with the roots.

`= (2)/(x^(2) )` if we want the x in the up part we just put negative the exponent

`= 2x^(-2)`
