They are: 2 times 81 = 162
Multiply and simplify 3^-2 x3^6
0.9^2=0.81 as 0.9^2=0.1*0.1*9*9=0.01*81=0.81 or 0.9 *0.9 -------- .81 .0 .0 0. ------- .81

How about: 8*81 = 648 or 2*324 = 648 out of many possibilities
You can multiple 9 x 9 to get 81
27 x 3 = 81
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)
You multiply 0.27 x 81.
9 x 9 = 81 :(
