Answer 1

Answer:

a) 4

b) 14

c) 4

d) 24

e) 149

Square roots:

a) 23

b) 42

c) 16

d) 43

e) 81

Step-by-step explanation:

We have to find the least number, which must be added to the given number to get the perfect square.

a) 525

Since , 525 is very close to 529 which is a perfect square;

So, the difference which we will get is 4;

And the square root of the perfect square 529 is 23.

b) 1750

Since , 1750 is very close to 1764 which is a perfect square;

So, the difference which we will get is 14;

And the square root of the perfect square 1764 is 42.

c) 252

Since , 252 is very close to 256 which is a perfect square;

So, the difference which we will get is 4;

And the square root of the perfect square 256 is 16.

d) 1825

Since , 1825 is very close to 1849 which is a perfect square;

So, the difference which we will get is 24;

And the square root of the perfect square 1849 is 43.

e) 6412

Since , 6412 is very close to 6561 which is a perfect square;

So, the difference which we will get is 149;

And the square root of the perfect square  is 81.
