Question 814699: I need help with figuring out how to transform (6sqrt(x^5))7 ("6" is the index) into an expression with a rational exponent. My lesson only included instructions on how to transform it without the "7" in there, so I just don't know what to do with it.
From what I've found I think it may be solved like this:
(6sqrt(x^5))7
(x^5/6)7
x^5/(6*7)
x^5/42
All I would need is an example, thank you very much for your time.
