and I can take the square root of 9.
is this correct?
The book I'm working from doesn't have the answers so I'm cross checking my work with Wolfram but Wolfram has a habbit of providing the same answer but in a totally different format. If I'm wrong please explain why thank you
This is the solution from Wolfram
**EDIT** as I relook over the problem, maybe the answer might be ?
I'll say I need to do something like this so now I have the denominators all the same, now what? I could take the cube root of most things?
I'm lost here...
**EDIT** nah that surely isn't right, the 4th root is making it confusing
There should be no reason to multiply by if you are going to simplify it immediately. You could simplify it before bringing them into 1 fractionI'll say I need to do something like this
Learn the rules of indices for taking roots. When you have that is equal to which in turn is equal to
