3 to the power of 1 is 3. 3 to the power of minus 2 is equal to 1 over 3 to the power of 2. 3 to the power of 2 is 9. 3 to the power of 1 times 3 to the power of minus 2 is the same as... 3 divided by 3 to the power of 2. So that gives us 3 divided by 9 which is the same as 1/3.
- 1 to the power 2 = 1 and to the power 3 takes you back to -1.
3^-1 = 1 over (3 to the power of 1) = 1/3, one third. a minus power is the same as a normal power but with a 1 above it.
1/3
Using symbol "^" for power. 2^(-3) is 1 / (2^3). 2^3 means 2x2x2.

-3^1 = -3
1/3
(3)-1 = 1/3
3^-1 x 3^2 = 3^1 = 3 1/3 x 9 = 9/3 = 3
3n+2 + (3n+3 - 3n+1) = 3n+1+1 + (3n+1+2 - 3n+1) = 3*3n+1 + (9*3n+1 - 3n+1)= (3+9-1)*3n+1 = 11*3n+1.

You can only do it if the power is an integer. If the power is a positive integer, then it represents multiplication of the same number of "bases". Thus, 34 = 3*3*3*3 or 85 = 8*8*8*8*8 Also any number to the power 0 is equal to 1. Finally, a number raised to a negative number is the same as its reciprocal raised to the corresponding positive power. Thus 3-4 = (1/3)4 = (1/3)*(1/3)*(1/3)*(1/3)
