Answer:
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
