Question

find the integral of e^(5-2X)

Answer 1

the first step is to remember your algebraic rule of exponents... \[\huge a^{b - c} \implies \frac {a^b}{a^c}\]
so can you turn e^(5-2x) into that form?

Answer 2

integral by subs, let u = 5-2x

Answer 3

i think u have forgot about dx for the last equation, right ?
