As it is clear that square of 9 or (9)^2=81
but you can do it in this way to0
9=10-1
so calculate this way
(10-1)^2=square of 10 + square of 1 -2 x 10 x 1
so 100 + 1 - 20=81

you can check for others too let take (19)^2
(20-1)^2=square of 20 + square of 1 - 2 x 20 x 1
400 +1-40
=361

(18)^2= (20-2)^2= square of 20 + square of 2 - 2 x 20 x 2
=400+4-80
=324

Squaring a number means multiplying that number by itself. For example, the square of 2 is 2 x 2 which equals 4.

Following the same logic, the square of 9 is 9 x 9 which equals 81.

The square of a number is mathematically represented by the number with a superscript ( 2) immediately after it. See the picture below.
