First divide 3 into 81
81 ÷ 3 = 27 so 81 = 3 × 27
Next divide 3 into 27
27 ÷ 3 = 9 so 27 = 3 × 9 and hence 81 =3 × 27 = 3 × 3 × 9
But 9 = 3 × 3 and thus
81 = 3 × 3 × 9 = 3 × 3 × 3 × 3 = 34
9 to the power of 2 = 81
92 = 81 AND 3^4
9 to the second power :))
I think it's 92
81.
9 to the 2nd power (92) 3 to the 4th power (34)
3 to the fourth power=81Three to the fourth power is 81.
3 to the power of 4 9 to the power of 2 81 to the power of 1 I'm on this problem in my notebook too ;)
81+0=81
Do you mean? 8.1 X 10^-1 Or. 0.9^2
81/100
81,000 is 81 thousands.0.081 is 81 thousandths.
