Question

9. How many non-perfect square numbers lie between the squares of the following numbers?
ii. 27 and 28
lli, 101 and 102
L 11 and 12
10. Observe the following pattern​

Answer 1

Explanation:

ii. 729 and 784( squares of 27 and 28)

The non-perfect square numbers which lie between these numbers are 730,731,732,734,735,till783.

iii,10201 and 10404

The numbers are 10202,10203,10204,10205,till10403.

L 121 and 144

The numbers are 122,123,124,125,till143.

Answer 2

729 and 784 are both squares of 27 and 28

So all numbers that are ending with 2,3,7,8 Are not perfect squares

So all the numbers between 729 and 784 ending with 2,3,7,8 are not perfect squares for example

732,733,737,738 and so on...

So there are 22 nonperfect squares between these two numbers...

The same will be done with the next two parts...
