just need some help with these if i integrate

5

x

do i just end up with x

and second i have

4

cube root x^2

the 4 and the x^2 mess things up for me and i dont know what to do

and if i have

1

cube root x

Hi there

Wow, that is very hard to read

1) $\displaystyle \int \frac 5 x dx = 5 \int \frac 1 x dx = 5 ln|x| + CONST$

2) $\displaystyle \int \frac{4}{\sqrt[3]{x^2}} dx = 4 \int \frac 1 x^{2/3} dx$

$\displaystyle = 4 \int x^{-2/3} dx = 4 * 3 * x^{1/3} + CONST$

Done

Yours,
