## amurciano2 one year ago How do I integrate 5^x/ln5

1. misty1212

$\int b^xdx=\frac{b^x}{ln(b)}$

That helps me with the top part what do I do with the ln5 in the denominator? Do I have to do u-sub?

Never mind I get it you place ln5 outside

Also it might help to look at this like this: $5 = e^{\ln 5}$ $5^x = e^{x\ln 5}$ So really when you take the derivative, that's why you get that extra $$\ln 5$$ term.
