10^2 = 100 10^1 = 10 10^0 = 1 10^-1 = .1 10^-2 = .01 If you can remember one of them you can remember all of them. If you know that .01 is one one-hundredth (1/100) then you can change that to 1/(10^2) and then flip the sign of the power and bring the 10 to the numerator to get 10^-2.
1 to any integer power is 1.

Here is how to think of and see the answer. 10 to the 0 power is 1 10 to the 1 power is 10, that is 1 with 1 zero 10 to the 2nd power is 100, that is 1 with 2 zeros we continue on until we get to the 9th power and 10 to the 9th is 1000000000 which is 1 with 9 zeros.

By definition of powers, x to the power y = x*x*x*........y times x to the power 1 = x Therefore, 10 to the power 1 = 10.
10 to the power 0 is 1
10 to the 0 power is 10 and 5 to the 0 power is 5 so 10 multiplied by 5 equals 50.
10 to the power 3 means 10*10*10, or 1000 10 to the power MINUS 3 means 1 over 10 to the power 3, so 1/1000.

10-1 is 10/-1 equals 0.1
1 times 10 to the 11 power
