(14*5)^2/5^2=

  • math -

    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
