The number 81 can be expressed in index form as ( 3^4 ), since ( 3 \times 3 \times 3 \times 3 = 81 ). Alternatively, it can also be represented as ( 9^2 ) since ( 9 \times 9 = 81 ).
81 = 92
No, -81 is not an irrational number because it can be represented in the form x/y = -81
In index form, 90 can be expressed as 9^2. This is because the index form represents the number as a base raised to a power, where the base is 9 and the power is 2. This is equivalent to 9 * 9, which equals 81.
In binary form it is 1010001.
Just writing "81" is mathematical enough for my taste. After all, that's a number, and numbers are mathematical.
