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

Simple

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.

I'm guessing you mean "what's the square of 9 squared". I live in USA, and I think that's how Americans say. It might be different in European countries. Anyway, 9 square, or square of 9 means 9^2, which means 9*9, which equals 81.

...If what you meant to ask is what is nine squared, the answer is 81. If on the other hand, you meant to ask what is the square ROOT of nine, the answer is three.

Thank you for your question.

A number is considered "squared" when it is multiplied by itself.

The square of 9 would be 9 x itself, or 9 x 9.

9 x 9 = 81

So the square of 9 = 81.

The square of 9 means raising 9 to the power of 2,

i.e. 9^2 assuming that the symbol ^ represents 'the square of'

so, 9^2= 9 times 9= 81

The square of 9 is 81

To square a number you will have to simply multiply the number with itself. So the square of 9 is 9*9=81

Square of nine is equal to eighty one

We can write it as

Square of 9

= 9 X 9

= 81

So the correct answer is 81

When you square a number, you simply multiply it by itself. Therefore, the square of 9 is equal to 9 x 9 = 81
