Hi I am new to specialist maths and I am pretty rusty with my algebra skills. Can anyone please tell me the steps to simplify this? Thanks.

Try factoring (3-x)^(1/3) out, and then making the negative exponent positive. After that, make a common denominator, and it should hopefully be straightforward from there.

That's correct

Thanks so much. I was very confused because the textbook answer was different... so the textbook must be wrong then?

Because the cube root is being squared, you can write (3-x)^2/3 as (x-3)^2/3 (they are the same thing).

Example:

Expand (x-3)^2 and (3-x)^2 (you'll get the same result)
