Answer 1

$\begin{gathered}\huge\star{\pink{\underline{\mathfrak{answer}}}}⋆ \\\end{gathered}$

Step-by-step explanation:

$3 \times 10 - {}^{8} = 3 \times \frac{1}{100000000}$

As there are eight zero's after one, therefore by dividing 100000000 , there will be 8 zero ahead of digit three.

$3 \times 10 {}^{ - 8} = 3 \times \frac{1}{100000000} =0.000000003$

Therefore, the usual form of 3×10−8 will be 0.000000003.

Answer 2

$3 \times {10}^{ - 8} \\ \\ = > \frac{3}{ {10}^{8} } = \frac{3}{100000000} = 0.00000003$
