This is my solution for the problem.......
First lets ignore kgrys
Next lets simplify the other side of the expression: (15625g2y3)1/3 * (15625g2y3)1/3
Since the expressions are the same on either side of the multiplication sign, I am going to work with:
A fractional exponent is a short hand way of writing roots. In this particular instance we are dealing with a cubic root. So you can rewrite the expression like this:
Now is there anything that you can take the cubed root....yes
The cubed root of 15625 is 25 and the cubic root of y3 is y.
So that leaves you with the expression:
If you transform the cubed root of g2 to a fractional exponent you get:
Now lets put that back into the expression:
25yg2/3 * 25yg2/3
or another way to write it is:
So now lets square the expression:
So the answers are:
