I didn't got it​

Answer 1

Step-by-step explanation:

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

Multiplying and dividing by 10,

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

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

( 1/10 = 10^(-1) )

$5 \times {10}^{ - 4}$

According to the rules of indices.
