Question

How can I differentiate this function. P=5Qe-0.1Q?

Answer 1

you want to do dP/dQ?

Answer 2

You will need the product rule, \[\frac{ d(f(x)g(x) }{ dx }=f'(x)g(x)+g'(x)f(x)\]

Answer 3

Yes i need dp/dq

Answer 4

so dP/dQ=5e^-0.1Q-0.5Qe^-0.1Q

Answer 5

Is it possible to find the value of Q if I were to equate the derivative to Zero?

Answer 6

yes it is

Answer 7

Is it 10?

Answer 8

1 second Ill have a pop

Answer 9

is P = 5Qe^0.1Q ?

Answer 10

P=5Qe^-0.1Q

Answer 11

Indeed it is 10, well done =)

Answer 12

Thanks

Answer 13

oh ok.now i get it
