It is: 9^2 = 81
81. 92 = 9 * 9 = 81
It is: (81*9*64)+19 = 46,675
5
It then equals 1/81
81 divided by 4 equals 20 with a remainder of 1.
The expression 3x3x3x3 represents 3 raised to the power of 4, which can be calculated as 3^4. This equals 81, since 3 multiplied by itself four times (3 x 3 x 3 x 3) results in 81.
