1. oh the answer is k they said the integral of the function i said to find from 0 to 2 is equal to the integral from 0 to 8

WHYYY

2. Why would you say that? I understand you use u subsitution u= x^3 and then eventually you get an integral from 0 2 of the function but i dnt understand why the integral from 0 to 2 and the integral from 0 to 8 would be the same?
