Question 133

What is the least number to be added to 4321 to make it a perfect square?

Solution

We need to find the approximate value of $$\sqrt{4321} \approx$$ 65.73

We find that $$65^2=4225$$ < $$4321$$ and $$66^2=4356$$ > $$4321$$

So the least number to be added = 4356 - 4321 = 35

$$\therefore$$ 35 can be added to 4321 to make it a perfect square.
