[ solve it by method i.e step by step without using calculator ]

or if there is any shortcut/trick plz mention !!​

Answer 1

Answer:

$0.2 \times {10}^{ - 3}$

Step-by-step explanation:

$4 {s}^{3} = 3.2 \times {10}^{ - 9} \\ = > {s}^{3} = \frac{3.2}{4} \times {10}^{ - 9} \\ = > {s}^{3} = 0.8 \times {10}^{ - 9} \\ = > s = \sqrt[3]{0.8 \times {10}^{ - 9} } \\ = > s = 0.2 \times {10}^{ - 3}$

As ' 0.2^3 = 0.8 ' and ' (10^-3)^3 = 10^-9 '
