Answer 2

Answer:

If we add 21 in the number it will make a perfect square of 39.

Step-by-step explanation:

To find : The least number which must be added to 1500 so as to get a perfect square number . Also find the square root of perfect square no ?

Solution :

The least number which must be added to 1500 so as to get a perfect square number.

We have to find the most closest perfect square in between the number lies.

i.e. $1444<1500<1521$

$38^2<1500<39^2$

We need to add $39^2-1500$ in the number.

Required number is $R=39^2-1500$

$R=1521-1500$

$R=21$

If we add 21 in the number it will make a perfect square of 39.
