Answer 2

Question :

Write in ordinary form :

• $\sf 8 \times 10^{-3}$

Answer :

$\sf 8 \times 10^{-3}$

We know that :

$\large \underline{\boxed{\bf{a^{-m} = \dfrac{1}{a^{m}}}}}$

$\sf : \implies 8 \times 10^{-3} = 8 \times \dfrac{1}{10^{3}}$

$\sf : \implies 8 \times 10^{-3} = 8 \times \dfrac{1}{10 \times 10 \times 10}$

$\sf : \implies 8 \times 10^{-3} = 8 \times \dfrac{1}{1000}$

$\sf : \implies 8 \times 10^{-3} = \dfrac{8}{1000}$

$\sf : \implies 8 \times 10^{-3} = 0.008$

$\large \underline{\boxed{\bf{8 \times 10^{-3} = 0.008}}}$

$\pink{\bf Hence, \: ordinary \: form \: of \: 8 \times 10^{-3} = 0.008}$
