Answer 1

Resposta:

36

b

Explicação passo-a-passo:

$( - 18a {}^{3} b4) \div ( - 2a {}^{3} b {}^{2} ) \\ ( - 72a {}^{3} b) \div ( - 2a {}^{3} b {}^{2}) \\ 72a {}^{3} b \div (2a {}^{3} b {}^{2} ) \\ \frac{72a {}^{3}b }{2a {}^{3} b {}^{2} } \\ \frac{72b}{2b {}^{2} } \\ \frac{36b}{b {}^{2} } \\ \frac{36}{b}$
