Hi can you please help me differentiate these two questions and show me how, thanks:
h(t)=-1/4t^2 +5e^-2t
h(t)=-5t^3-4t^2 / ln(5t)
Thanks!
h(t)=-1/4t^2 +5e^-2t
h(t)=-5t^3-4t^2 / ln(5t)
Thanks!

Instead of dy/dx you have dh/dt. Just differentiate like normal. Quotient rule for 2nd question.

If you don't know what e or ln are then you probably need to go back a few steps before attempting questions asking you to manipulate/differentiate them.

Basically, if you raise e to any power, e^x, the gradient will be e to that power. y=lnx is the inverse function:

y=lnx => dy/dx=1/x
y=e^x => dy/dx=e^x
These videos should help:

You may also need to use the chain rule, as you have composite functions:
