How many non perfect square numbers and there between 9square and 10square

Answer 1

Hi there!
Here's the answer:

°•°•°•°•°•°<><><<>><><>•°•°•°•°•°•°

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
