Question 191863: I'd like to know how to simplify the following:
I'm not sure if I should eliminate the square root by putting parentheses around the entire expression and cubing it, or if I should pull x to the 5th out, leaving the problem as x to the 5th * the 3rd sqrt of 80x squared. And the same problem with the denominator...do I pull out z squared, leaving me with z squared * the 3rd sqrt of 9y. Or do I go with my first instinct and cube everything...leaving me with 512,000 x to the 51st/729 y3z18? Yikes. Any help would be greatly appreciated. Thanks in advance!
