Question

How do you find the indefinite integral of `int 5/x`?

Answer 1

`5ln(x)+C`

Explanation:

Think about derivatives that could equal `1/x`
We know that `d/dxlnx=1/x`
and using properties of integrals, we can place any constant to the front of the integral.
`5int1/xdx`; `5(lnx)+C`
You get your final answer.
