Answer 1

So what's the problem?

Answer 2

i don't understand how to find the radical expression

Answer 3

let me give you a series of example to help you visualize the answer\[\large x^{\frac 12} = (\sqrt x)^1\]
\[\Large x^{\frac 32} = (\sqrt x)^3\]
\[\Large x^{\frac 45} = (\sqrt[5]{x})^4\]
\[\Large x^{\frac 58} = (\sqrt[8]x)^5\]

do you have an idea what x^(4/9) is now?

Answer 4

ohhhh okay! yes! thank you so much!
