Question

Can someone please explain to me how to solve this?

For x≥0,
`√(x^5)` +
`√(9x)` =

(A) (x²+ 3)√x

(B) 10
`√(x^6)`

(C)
`√(x^5+9x)`

(D) x²+ 3

(E) 3x²

Answer 1

A

Explanation:

√(x^5) = x^(5/2) = (x^2)√x

√9x = (√9)(√x) = (3)√x

which means: ((x^2)√x) + ((3)√x)

since both have a √x, you can factor it out. for example...if you look at A, if you apply the distributive property you can see it expands back out. hmu if you need a different. explanation
