Answer 1

Answer:

Following are the solution to the given question:

Step-by-step explanation:

In question a:

$\to 16= 4^2$  is a perfect square.

$\to 125 = 5^3$ is not a perfect square

In question b:

$\to 20 = 2 \times 2 \times 5$, not a perfect square.

$\to 25 = 5^2$ is a perfect square .

$\to 100 = 10^2$ is a perfect square .

$\to 125$ is not a perfect square, its nearest perfect square is$121 = 11^2 .$

$\to 144 = 12^2$  is a perfect square .

$\to 225 = 15^2$  is a perfect square .

$\to 10,000 = 100^2$ is a perfect square .
