x7w1 / x2w1
The "W" cancels out since w1 = w and  w/w = 1, so then we have x7/x2 = x5


 Cancellation of W can be viewed as subtraction of exponents of  W1-1 = W=1
 X7W/ XW = X5
  Use laws of multiplication and division of exponents with the same base.
     am / a = a m-n       Here your a is X , m is 7 and n is 2.
