You should also know a chunk of the powers of 2...

2^2 = 4 ... 2^3 = 8 ... 2^4 = 16 ... 2^5 = 32 ... 2^6 = 64 ... 2^7 = 128

Some of the 3's...

3^2 = 9 ... 3^3 = 37 ... 3^4 = 81

And how the 10's work:

10^1 = 10 ... 10^2 = 100 ... 10^3 = 1000 ... 10^4 = 10,000 ... 10^5 = 100,000

For the powers of 10, you just look at what the exponent says and put that many zeros on!  Easy!
