Question

expand the following (a) p^2 q^2 (b) a^3b^2 (c) (-a/b)^3.​

Answer 1

$a) {p}^{2} \times {q}^{2} \\ = p \times p \times q \times q \\ \\ b) {a}^{2} \times {3b}^{2} \\ = a \times a \times 3b \times 3b \\ \\ c) { \frac{ - a }{b} } ^{3} \\ = \frac{ - a}{ b} \times \frac{ - a}{b} \times \frac{ - a}{b}$
