What is the best way to go about solving...? d/dx (2x + 5)^(4x)

OpenStudy (johnt):

\[(2x + 5)^{4x}\]

OpenStudy (amistre64):

log it

OpenStudy (johnt):

like this?\[\ln y = \ln (2x + 5)^{4x}\]

OpenStudy (amistre64):

yep, ow the 4x pops out front and you can work a product rule and a log rule

OpenStudy (johnt):

simplify, and then derive both sides to get y' ?

OpenStudy (amistre64):

*now ,,, not ow lol

OpenStudy (johnt):

Is there any other way to solve it, that would be taught in Calc 1?

OpenStudy (amistre64):

that should be taught in calc1 .. calc 1 is all about derivatives

OpenStudy (johnt):

Sorry, I was unclear. Logarithmic Differentiation is taught in my Calc 1 class. Is there an alternate way that would also be taught in Calc 1?

OpenStudy (amistre64):

none that i can readily see .... was thinking how to do a substitution but nothing really comes to mind

OpenStudy (johnt):

Ok, thanks!
