MA power has two parts. Base and Exponent. A number 423 in base 10 can be written in other bases as well: 1. 4* 10^2 + 2*10^1 + 3*10^0 =...

Mmark2142 replied to the thread What major topics are there in arithmetic and what order to learn them?.But that is what i am asking. A power has two parts. Base and exponent. 1. 4* 10^2 + 2*10^1 + 3*10^0 = 423 2. 1*7^3 + 1*7^2 + 4*7^1 +...
