Laws of Exponents. Stuck!

Use the Law of Exponents to rewrite and simplify the expression.

(x^2n) * (x^3n-1)

(x^n+2)



*NOTE Everything that follows after the x's are meant to be in the exponent position, I couldn't figure out how to get all of them up there. I could only get one successfully because if I tried to ^ again in Latex it would look like x^2^n which looks like 2 is to the nth power. Anyways, please help. I am stuck. Am I missing a law I need to be using?


Thanks,
Sham

Re: Laws of Exponents. Stuck!

Use {} around the exponent (in latex). In text, use (),[], etc.

When multiplying powers with the same base, add the exponents. When dividing powers with the same base, subtract the exponents.
