Negative 9 times 9= Negative 81
The two squared numbers that divide to make 9 are 81 and 9. When you calculate (81 \div 9), you get 9, and both 81 (which is (9^2)) and 9 (which is (3^2)) are perfect squares.
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 :(
The two numbers that multiply to 81 and add to -18 are -9 and -9. When multiplied, they give -9 × -9 = 81, and when added, they result in -9 + -9 = -18. Thus, both conditions are satisfied with these numbers.

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.
36 and 45
81 and 4
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.
