Hi
Simplify using the law of exponents,where n is the positive integer.
1)x^n . x^2n
attempt
x^n+2n = x^3n
2)(x^n)^3n
attempt
x^n*3n =x^3n^2
3)(x^3+n)(x^3n-1)
attempt
I dont't know how to do it
Please tell me if my attempt are wrong and if they are please write in step so I can properly understand.
Thank you,
