simplify the following
14p(to the power2)q(to the power -2)
(5ab)All to the power -2 x 15a (to the power 2) x b (to the power 3)
(Exponents in the denominator can be subtracted from exponents in the numerator, or vice versa, if they are exponents of the same number).
1/q-2 = q^2
(5ab)^-2 * 15a^2b^3 =
15 a^2b^3/[25 a^2 b^2]
=(15/25)b = (3/5)b
