1 and 81 Those two numbers certainly divide into 81 though they are not the only numbers to do so.
81 and 9 if you add them. 4 and 25 if you multiply them.
9 x 9 = 81 :(
36 and 45
1 x 81, 3 x 27, 9 x 9.

170 * * * * * No. These are numbers of the form AB00 (9*9 = 81 of them) C0D0 (81 of them), and E00F (81 of them). 243 in all.
There are infinitely many different choices of 3 numbers that add up to 81. 50 + 30 + 1 = 81 40 + 40 + 1 = 81 10 + 11 + 60 = 81 etc.
81 and 4
36 and 45
16 and 81 are the only two.
39,39,1,1 (: If you mean multiplication, 1, 3, 9, 27, 81 are all factors of 81.
The only pair of positive single-digit numbers which give a product of 81 are 9 and 9.
25 and 81
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.
