simple question of two problems that are alike

1

the interval is 5 ≤ x ≤ 7, the function is y = [(x^4)/4] + [1/(8x^2)]

here, i just integrate function from 5 to 7, correct?

2

the interval is 1≤ x ≤ 9, but i am given an integral from one to x of √[(t^3) - 1]dx

i just replace x with 9 and evaluate, correct?

forgive english please! thank you
