eighty-one times one and nine times nine
They are: 3*27 = 81 and 3+27 = 30
34, 811, 92
1 and 567 or 81 and 7
81 x 24 = 1944
Well, darling, the product of 9 and 9 is 81. It's as simple as that. Math doesn't have to be a headache, you know.
1 times 81 and 9 times 9 (assuming you meant only whole numbers)
They are: 3*27 = 81 and 3+27 = 30
81
81 = 34 = 92 = 65610.5
The only pair of positive single-digit numbers which give a product of 81 are 9 and 9.
9^2 is 81 and 3^4 is 81
1 x 81 3 x 27 9 x 9
3^4 or 9^2
34, 811, 92
-9 and -9 multiply to get 81. ■
1 and 567 or 81 and 7
You can express 81 as a power in several ways: ( 81 = 3^4 ) because ( 3 \times 3 \times 3 \times 3 = 81 ). ( 81 = 9^2 ) since ( 9 \times 9 = 81 ) and ( 9 ) can be rewritten as ( 3^2 ). ( 81 = (3^2)^2 ) which simplifies to ( 3^{2 \times 2} = 3^4 ). Thus, all representations confirm that ( 81 ) can be expressed as a power in different forms.
