plz explain how you get this answer i am studying the sample questions for the math olympics tommorow so i need to know what they will be like.
I'll use the more common ^ instead of •, which is often used for simple multiplication.
10^5 = 10*10*10*10*10 = 100,000
it's a simple power.
3^2 = 3*3
2^6 = 2*2*2*2*2*2 = 64
and so on.
