Question

pls answer step by step ​

Answer 1

$\: \: \: \: \frac{72 {x}^{3} \times {2}^{2} }{18 {x}^{ - 2} \times {4}^{ - 3} } \\ \\ = \frac{72 {x}^{3} }{18 {x}^{ - 2} } \times \frac{ {2}^{2} }{ {4}^{ - 3} } \\ \\ = \frac{3 {x}^{3} }{ {x}^{ - 2} } \times \frac{ {2}^{2} }{ { {2}^{2} }^{( - 3)} } \\ \\ = 3 {x}^{(3 - ( - 2))} \times \frac{ {2}^{2} }{ {2}^{ - 6} } \\ \\ = 3 {x}^{(3 + 2)} \times {2}^{(2 - ( - 6))} \\ \\ = 3 {x}^{5} \times {2}^{(2 + 6)} \\ \\ = 3 {x}^{5} \times {2}^{8}$
