Q.

Write each number as a power of

5

.

\newline

a

0

.

2

\newline

b

25

Express $0.2$ as Power of $5$ : a) We need to express $0.2$ as a power of $5$ . $0.2$ is the same as $1/5$ . $1/5$ is $5$ to the power of $-1$ . So, $0.2 = 5^{-1}$ .
Express $25$ as Power of $5$ : b) Now, let's express $25$ as a power of $5$ . $25$ is $5$ times $5$ . That's $5$ to the power of $2$ . So, $25 = 5^2$ .
