Question
Express the following in usual form: $1.75 × 10^{-3}$
✓
Answer
Here, $1.75\times10^{-3}=\frac{175}{100}\times\frac{1}{10}^{3}$
$=\frac{175}{100000}=0.00175$ $\Big[\because\text{a}^{\text{-m}}=\frac{1}{\text{a}^{\text{m}}}\Big]$
$=\frac{175}{100000}=0.00175$ $\Big[\because\text{a}^{\text{-m}}=\frac{1}{\text{a}^{\text{m}}}\Big]$
