Please do not use "x" as multiplication sign; standard is now "*" You had this to simplify: Code: 5 * k^3 * k^2 ^2 * (k)^5 * k^2 k  5 * k^2 Code: 5 * k^3 * k^2 ^2 k So now you need only worry about (k)^5 * k^2 And that simplifies to k^7 So wrap up: 5k^6 * (k^7) = 5k^13 That's just a suggestion as to steps to follow; in other words, do the easiest/obvious first.
