Question

1) Simplifique:

A) (x elevado a 5 ÷ x²) . (x elevado a 7 ÷ x⁴)

B) (a² × x)² . (a . x)³

Answer 1

$a) \: {x}^{5} \div {x}^{2} \times {x}^{7} \div {x}^{4} \\ {x}^{5} {x}^{ - 2} {x}^{7} {x}^{ - 4} \\ {x}^{5 - 2 + 7 - 4} \\ {x}^{6} \\ \\ b) \: ( {a}^{2} x)^{2} \times (ax)^{3} \\ {a}^{4} {x}^{2} {a}^{3} \: {x}^{3} \\ {a}^{7} {x}^{5}$
