You should get a TI-89 or some other form of computer algebra system. They are great with integrals. And if you're not supposed to use technology, well, what do you think we're all doing?

It might help to recognize that x^2 (sqrt(x) is the same as x^(5/2). You can use the same approach you've used in class for integrals of x^2, x^3, etc., but with this fractional exponent.

take the antiderivative. of the function. then take the value of the antiderivative at x=2 and subtract that from the value of the antiderivative at x=4.
the easiest way to find the antiderivative is to use integration by parts.

query::sure indispensable of (x-4)/(x^2) from a million to 2 Now,(x-4)/(x^2) =x/x^2-4/x^2 =a million/x-4*(a million/x^2) So,? (x-4)/(x^2) dx =?(a million/x)dx-4?(a million/x^2)dx =lnx-4*(-a million/x)+C =lnx+4/x.+C returned sure indispensable of (x-4)/(x^2) from a million to 2 =ln2+2-ln1-4 = ln2-2 subsequently, U ARE marvelous.

If I read it right, the function is x ^ 2.5 ?
Now can you do it?
