Answer:
n = 15
Step-by-step explanation:
(x^n)(x^5)^3 = x^30
(x^n)(x^15) = x^30
x ^ (n+15) = x^30
n + 15 = 30
n = 15
To do the question, you need to know the exponent rules, which are short cuts to be able to do exponent work.
If you raise a power to a power, then times the exponents.
If you are multiplying two terms with the same base (in this case, x; the base is the large font bottom number) then ADD the exponents.
