i think that top thing is a u sub

Answer 7

yes...

Answer 8

the x on the outside is a derivative of the inside

Answer 9

with some modifications that is

Answer 10

u = 4+2x^n

du/dx = 2n x^(n-1)

du/2n = x^(n-1) dx

Answer 11

where n is considered to be constant

Answer 12

For the second integral you could use u-substitution with u = x²+7x-4.

Answer 13

Then du/dx = 2x+7.

Answer 14

doh!! whyd i take the hard one lol

Answer 15

How can i set this up can someone draw it out fully fo me

Answer 16

\[\frac{\int u^{1/2}du}{2n}\]
then integrate like normal

Answer 17

ok

Answer 18

the final results you really need to obtain on your own tho

Answer 19

gives you that sense of accomlishment :) and its in a normal looking integration that you should be able to manipulate now
