[tex]\int 5\sqrt{x} = \int 5x^{1/2}[/tex]

So just use the power rule for integrals.

the actual problem is:

Evaluate the definite integral [tex]\int^{7}_{1}[/tex] 5/[tex]\sqrt{}x[/tex]

using the power rule I got:

5[(x^3/2)/(3/2)] evaluating them at the end points 1 and 7, the answer I get after using FTC II is:-58.400 and is incorrect.

What am I doing wrong? please help

If so, then x^(3/2) shouldn't be part of your answer.

Yes (to part one)

If so, then x^(3/2) shouldn't be part of your answer.

then how should I find the antiderivative? for 5/[tex]\sqrt{}x[/tex]
