Question

Solve: 1700=300e^(r*11) for r

Answer 1

I used the formula A=Pe^(rt) to form this equation

Answer 2

1700/300=e^(r*11)

Answer 3

1700/300 =e^(r*11)
e^(r*11) =17/3
taking log both sides we have ln e^(r*11) = ln (17/3)
11r lne =ln17 -ln3
or r = (ln17 -ln3 )/11 as lne=1

Answer 4

ok thank you very much. the key is to ln both sides and bring down the exponent then.

Answer 5

yup
welcome
