Hello,
First off we can rewrite this as:
(sqrt 64 sqrt x^5) / (sqrt 121 sqrt x^7) Then we can get:
8 sqrt x^5/ 11 sqrt x^7 We can now rewrite this as:
8(x^5/2)/11 (x^7/2) Now bring this denominator up with the numerator:
8 (x^5/2)(x^-7/2)/11 This will result in:
8 (x^-2/2)/11 Now we can rewrite it as:
8/11x
Make sense?
