Question

how many non perfect squares are lies between 18 and 19 ?

Answer 1

Answer:

hope it was helpful

mark me as the brainliest

The No. of Non perfect squares lying between two consecutive square No. a² and (a+1)² is given by

N= 2 × base of first Number. = 2a

where a = first Number

The No. of Non-Perfect squares between 9² and 10²

= 2× 9

= 18

Verification:

10²= 100

9²= 81

100-81 = 19

Here one one of the no. is included (100 or 81)

If this one No. is excluded, we get the No. of Numbers that LIE BETWEEN 81 and 100.

19-1= 18
