if you have different numbers you just have to leave it or multipy it out or simplify it so they are the same and can combine exg 6^2 times 5^3 cannot be combined but if you have 2^4 times 4^2 that means2^4 times (2^2)^2=2^4 times 2^4=2^8 heere are some exponential laws for if you have the same number
