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
(x^n)(x^m)=x^(n+m)
(x^n)^m=x^(nm)
(x^n)/(x^m)=(x^(m-n))
