Question

I need help simplifying this radical expression

Answer 1

`x^4y^9`

Explanation:

We can simplify this radical expression by expanding the expression inside the radical:

`√(x^8y^1^8)` is the same as:

`√(x^4*x^4*y^9*y^9)` since the exponents ultimately add up. This can be further simplified into:

`√((x^4)^2*(y^9)^2)`, and since the 2 values are being squared, and the square root operation is the inverse of that, it cancels out:

`x^4y^9`
