The number 9 !
You are asking for the square root. The square root of a number is a number multiplied by itself to get that number. For example, the square root of 81 is 9, because 9 X 9= 81. The square root of 1000 is not a whole number, it is 31.62 (rounded) because 31.62 x 31.62 = 1000.(31.62 is approximate. The actual number is 31.6227766)
The number 9 !
A number "squared" is just a number multiplied by itself. So just work up:1*1=12*2=43*3=94*4=165*5=256*6=367*7=498*8=649*9=81
Anything you want to be multiplied by 81.
27 multiplied by 81 is 2,187.
The number is three.
9 x 9
Oh, dude, that's like some math stuff right there. So, if you're looking for a number that you can multiply by itself three times to get 81, you're basically asking for the cube root of 81. And guess what? The cube root of 81 is 3! So, yeah, 3 multiplied by itself three times equals 81. Math can be cool sometimes, I guess.
Oh, what a happy little math problem we have here! To find the number that, when multiplied by itself 4 times, equals 81, we simply need to take the fourth root of 81. So, the number we are looking for is 3. Isn't it wonderful how numbers can come together to create harmony and beauty?
When a number is squared, it means that it is that number is multiplied by itself. So in this case it would be 9x9 which is equal to 81.
The number that multiplied by 32 would equal 81 is 2.53125.

The square root of 81 is: ±9 (9 or -9)A square root is a number which, when multiplied by itself, equals the original number. As 9 x 9 = 81 and -9 x -9 = 81, the answer is plus or minus nine.
If multiplied by a number, it would equal 81%. ie, 100*.81=81
