Question

Pls answer(a) one with full steps pls don't give rubbish answers

Answer 1

$\frac{{(2 {x}^{2})}^{3} }{ {(5x)}^{ - 2} } \\ \\ = \frac{ {(2)}^{3} \times {( {x}^{2} )}^{3} }{ \frac{1}{ {(5x)}^{2} } } \\ \\ = {(2)}^{3} \times {( {x}^{2} )}^{3} \times {(5x)}^{2} \\ \\ = 8 \times {x}^{6} \times 25 \: {x}^{2} \\ \\ = 8 \times 25 \times {x}^{6} \times {x}^{2} \\ \\ = 200 \: {x}^{(2 + 6)} \\ \\ = \boxed{ \large{ 200 \: {x}^{8} }}$
