Question

Find least number that must be added to 1500 so as to get a perfect square.also find square root of the perfect square

Answer 1

Solution:

Let x be the least number that must be added to 1500.
x+1500=perfect square
if x is equal to 21, then
21+1500=1521.
And the square root of 1521 is 39.

Therefore, the least number that added to 1500 to get the perfect square is 21.

Answer 2

Step-by-step explanation:

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<15211444<1500<1521

38^2<1500<39^2382<1500<392

We need to add 39^2-1500392−1500 in the number.

Required number is R=39^2-1500R=392−1500

R=1521-1500R=1521−1500

R=21R=21

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