There is only one number that's equal to 81. That number is 81.

There are many other sets of two or more numbers that you can manipulate

with an arithmetic operation and produce 81 as the result. For example:

Addition: 27 + 54 = 81

Subtraction: 175 - 94 = 81

Multiplication: 3 x 27 = 81

Division: 567 / 7 = 81

But none of those other numbers is "equal" to 81.

1 x 81 3 x 27 9 x 9

3 * 27

1 and 81 Those two numbers certainly divide into 81 though they are not the only numbers to do so.

There are no two real numbers that will add to -9 and multiply to 81. Using complex numbers, the two numbers are: (-9/2 + i9/2√3) and (-9/2 - i9/2√3)

They are: 9 times 9 = 81

9 x 9 = 81 These numbers go into 81: 1, 3, 9, 27, 81.

How about: 40+41 = 81

1 x 243, 3 x 81, 9 x 27

2.4115 and 33.5885 (to 4 dp)

the numbers are 1296 and 81

1 x 6561, 3 x 2187, 9 x 729, 27 x 243, 81 x 81.

Negative 9 times 9= Negative 81

1 x 243, 3 x 81, 9 x 27 = 243

79 and 2 if you add them.

1 x 81, 3 x 27, 9 x 9.

81 = 1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1.

1 x 81, 3 x 27, 9 x 9
