$\times {10}^{3}$

Answer 2

The answer is $\frac{1}{625}$

Step-by-step explanation:

We need to find the value of 5^-4.

It can be written as $5^{-4$

Since the power term contains a negative sign, we can make it positive by writing the number in fraction form as $\frac{1}{5^4}$

Now, when we can find the value of the term as follows

$\frac{1}{5^4}$  $=\frac{1}{5\times5\times5\times5}$ $= \frac{1}{25\times 25}$ $=\frac{1}{625}$
