Answer 1

$\bf{ -16000}$

Solution

$\:\:\:\implies16^{ \frac{1}{2} } \times 10 ^{ - 3}$

$\:\:\:\implies\{({4})^{4}\}^{ \frac{1}{2} } \times {10}^{ - 3}$

$\:\:\:\implies{4}^{\cancel{4} \times \frac{1}{\cancel{2}}}\times10^{-3}$

$\:\:\:\implies 4^{2}\times10^{-3}$

$\:\:\:\implies16\times-1000$

$\:\:\:\implies\bf{-16000}$
