The number 4312 in base ten is (4*10^3) + (3*10^2) + (1*10^1) + (2*10^0)

4312 in base six is (4*6^3) + (3*6^2) + (1*6^1) + (2*6^0) which is 980

therefore 4312 in base six is equal to 980 in base 10

QUESTIONS:

a) does 124 in base 5 represent an odd number?

b) how can you tell if a number is odd in base 10 by looking t its base 5 representation

2. Relevant equations
