Question

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

Answer 1

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

Answer 2

log it

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

*now ,,, not ow lol

Answer 7

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

Answer 8

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

Answer 9

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?

Answer 10

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