This expression can be evaluated directly with a calculator. But I believe this is not the idea of the problem.

We can apply to our advantage some of the basic rules of exponents, one of which can be applied: if numerator and denominator are raised to the same power, the division can be done before raising powers.

(14*5)²/(5²)

=(14*5/5)²

=14²

=196
