Question

Evaluate the given integral using the substitution (or method) indicated.
e^(x/8) dx; u = x/8

Answer 1

u = x/8

du = 1/8

So the integral e^(x/8) = 1/8 e^u du

Answer 2

\[\int\limits_{}^{}e^{\frac{ x }{ 8 }}dx\]

Sound right?

Answer 3

= 8 e^(x/8) + C

Answer 4

ASSUME t=x/8 the du=dx/8 substitute dx=8du
