Question

HELP PLEASEEEEEEE!!!!!!!!

Answer 1

0.1764

0.2025

Explanation:

Let x be a perfect square such that √x lies between 0.4 and 0.5

Then y = √x

Then we have the inequality
0.4 < √x < 0.5

==> 0.4 < y < 0.5

So the number x must lie between 0.4² = 0.16 and 0.5² = 0.25

So the square of any number between 0.4 an 0.5 will be a perfect square fitting the requirement

Let's take y = 0.42. Then y² = 0.42² = 0.1764

y = 0.45 gives y² = 0.2025

So two perfect squares whose square root values lie between 0.4 and 0.5 are 0.1764 and 0.2025

In fact squaring any value between 0.4 and 0.5 will provide such a number
