### Theory:

Let us now see how we can convert the numbers in standard form to usual form.
Standard form to usual form.

1. Expand the given ${10}^{n}$ and multiply it by the given number.

2. Then the result will be in the usual form.
Write the following numbers in usual form.

i) $1.0867×{10}^{4}$

The given number is $1.0867×{10}^{4}$.

Expand the ${10}^{4}$ and multiply it by the given number.

$1.0867×{10}^{4}=1.0867×10000=10867$

Therefore, the usual form of $1.0867×{10}^{4}$ is 10867.

ii) $0.8×{10}^{-2}$

The given number is $0.8×{10}^{-2}$.

Expand the ${10}^{-2}$ and multiply it by the given number.

$0.8×{10}^{-6}=0.8×0.01=0.008$.

Therefore, the usual form of $0.8×{10}^{-2}$ is 0.008.
