10 to the 1st power = 10*1???

10 to the 0 power = 10*0???

I'm not sure.

• math -

I don't get how 10 to the 0 power equals 1

• math -

...
10^3 = 10*10*10
10^2 = 10*10
10^1 = 10
10^0 = 1
10^-1 = 1/10
10^-2 = 1/100
...

• math -

or, if you know the laws of exponents,

10^m / 10^n = 10^(m-n)

if m=n, say 3,

10^3/10^3 = 10^(3-3) = 10^0
but 10^3/10^3 = 1

10^(m-m) = 10^0 = 10^m/10^m = 1
