Answer 1

$\frac{1}{400}=0.0025$

Solution Steps:-

$\left(\frac{1}{5}\times 4^{-1}\right)^{2}$

$\left(\frac{1}{5}\times \left(\frac{1}{4}\right)\right)^{2}$

$\left(\frac{1}{20}\right)^{2}$

$\frac{1}{400}$

We get the answer.

$\frac{1}{2 ^ {4} \cdot 5 ^ {2}} = 0.0025$

$Calculate \: 5 \: to \: the \: power \: of \: -1 \: and \: get \frac{1}{5}.$

$Calculate \: 4 \: to \: the \: power \: of \: -1 \: and \: get \: \frac{1}{4}.$

$Multiply \frac{1}{5} and \frac{1}{4} to \: get \frac{1}{20}.$

$Calculate \: \frac{1}{20} \: to \: the \: power \: of \: 2 \: and \: \\ get \frac{1}{400}.$

And we get the answer.

Don't write these all.
