Answer 1

$\Huge \pink {\underline {\mathbb {ANSWER:}}}$

As we know that when we multiply two integers or two same variables, their power gets added and when we divide two integers or two same variables, their power gets subtracted. So, by using the BODMAS rule, we get

$\LARGE \purple {\tt {{2h}^{-10} \times {h}^{4} \div {2h}^{-3}}}$

$\LARGE \purple {\tt {\leadsto {2h}^{-10} \times {h}^{4} \div {2h}^{-3}}}$

$\LARGE \purple {\tt {\leadsto {h}^{-10} \times {h}^{4} \times {h}^{-3}}}$

$\LARGE \purple {\tt {\leadsto {h}^{-10 + 4 - 3}}}$

$\LARGE \purple {\tt {\leadsto {h}^{-9}}}$

$\Huge \purple \leadsto \pink {\boxed {\tt { \frac{1}{{x}^{9}}}}}$
