I know that the answer is dy/dx = 6^x In x. I just do not understand the steps!
Thanks for ANY help!!!

log y = x log 6
d/dx (log y) = log 6
d/dy(log y) (dy/dx) = log 6
(1/y) (dy/dx) = log 6
(dy/dx) = y log 6
dy/dx = (log 6)(6^x)

y= 6ⁿ
y'=?

well lets just take this as our equation for a sec:

y= kⁿ where k = a constant
y' = ln(k) kⁿ

so y'= 6ⁿ =
y' = ln(6) 6ⁿ

Just a rule you have to remember.

It may look like the eⁿ which when you take the derivative is itself but that is a different case so be careful not to get those two mixed up.

Hope that was helpful!

y=6^x
Take ln on both sides
ln y = x ln (6)
Differentiate both sides
(1/y) dy/dx = ln (6)
Multiply both sides by y or solve for dy/dx
dy/dx=y ln(6)
i.e. dy/dx=6^x ln(6)

y = 6^x

take natural log on both sides

ln(y) = ln(6^x)

ln(y) = xln(6) [since lna^b = b*ln(a)]

now differentiate with respect to x using product rule

(1/y)dy/dx = x*(0) + ln(6)*1

(1/y)dy/dx = ln(6)

multiply with y

dy/dx = y*ln(6)

substitute back y = 6^x

dy/dx = 6^x ln(6)
