Add the coefficients and variables of your terms.

you would have \[5x^5*x^8*2y^10\rightarrow (5x^13)(2y^10)\]
x^5*x^8=x^13 that is how i got x^13 then just put everything back together
and you get 5x^13*2y^10

forgot to multiply the coefficients so you would get 10x^13*y^10

welcome anytime just remember that coefficients you multiply and variable with powers you add

so we have \[k^3(k^\frac{ 7 }{ 3 })^-5 \rightarrow (k^\frac{ 16 }{ 3 })^-5\]
so we have [k^(16/3)]^-5

whattt....for the problem itself is the k^3*(k^7/3)^-5 ? cause i got a totally different answer

for the problem you wrote down are we trying to simplify k^3*(k^7/3)^-5 ? or did i get it wrong because none of the answers you posted did i get
