given the expression
x^2/x^2 . x^2
we should find its equivalent
so,
x^2/x^2 . x^2
from what we are given, x^2 at the numerator will cancel out one of the x^2 at the denominator.
so we have
1/1 . x^2
recall anything multiplied by 1 remains the same
so our final answer will be
1/x^2
so the equivalent expression is 1/x^2
so the correct option is the last option whish is 1/x^2
