Question

Can someone help me with this calc2 questions
integral of x5^x dx. I know that you have to integrate by parts, but I am not sure how do to that with this problem.

Answer 1

you'll need this

\((5^x)' = 5^x .ln5 \) or \(\int 5^x \ dx = \ \frac{1}{ln5}.5^x\)

so set it up with \(u = x \) and \( v' = 5^x\) and plough away

ask if help needed :p

Answer 2

\[x *\exp (x \ln5) \] will be easy for integral by parts @IrishBoy123

Answer 3

sweet as a nut, @dinamix !!

Answer 4

i gave him easy metohd Mr. irish

Answer 5

lol

Answer 6

How do you integrate 5^x/ln5

Answer 7

\(\large \int \frac{5^x}{ln5} = \frac {1}{ln5}\int 5^x\) and i posted that integral in my first post :p
