Question 72

State whether the following statement is true or false:

The square root of a perfect square of n digits will have $\left(\frac{n+1}{2}\right)$ digits, if n is odd.

Answer 1

True
If the square has 3 digits, then its square root has 2 i.e. $\left(\frac{3+1}{2}\right)$ digits.
Similarly, if the square has 5 digits, then its square root has 3 i.e. $\left(\frac{5+1}{2}\right).$
