a manufacturer's cost is given by C= 300 cube root of n + 1200, where c is the cost and n is the number of parts produced. find the cost when 8 parts are produced. help please!!!!

We have C = 300n^{1/3} +1200

Substitute 8 for n to get

C = 300*8^{1/3} +1200

You should know that 2^{3}=8, so what is 8^{1/3}?
