The answer is $20 because 38+38=66. So you would have to subtract 62 from 66 which is $4. Than you would multiply $4 by 5 which will get you $20. So the answer is $20
(The numerator and the denominator has same bases, therefore the powers will get subtracted. It is an exponential property)
(As the left hand side is equal to right hand side and the bases are on both the sides are equal too, we will equate their exponential power. Another property)
