Answer 2

Question
$100 \times {10}^{ - 6}$
According to Law of Exponent
If
${a}^{ - x}$
Then It will be
$\frac{1}{a} {}^{ - x}$
Now if
$10 {}^{ - 6} \\ = {( \frac{1}{10}) }^{6} \\ \frac{100 \times 1 \times 1 \times 1 \times 1 \times 1 \times 1}{10 \times 10 \times 10 \times 10 \times 10 \times 10} \\ = \frac{1}{10000}$
It can be written as
${10}^{ - 4}$
As it have 4 zeros
$\boxed{\mathbf{Answer={10}^{-4}}}$
