ln(x+5) - lnx =1Assalamo'alaikum, I need help with this question:
Solve the equation
ln(x + 5) = 1 + lnx,
giving your answer in terms of e.
i'm home studying and no one around can help me right now.
ln(x+5) - lnx =1
thanks. how about this one, how do you differentiate x = 4t/(2t + 3)?
Question 7 (ii)Which Question?
Its quite simple for the question 7 part 2 just do it like
3/(1 + 2x)^2 < 1/3 and then solve for x in the next step you will get like this
(1 + 2x)^2 (>)9
then
once when you solve it using the (a+b)^2 formulae you will get it like 4x^2 + 4x +1>9
you will get like
4x^2 +4x -8 and then solve it quadratically......ok get it like x > 1, x < –2 ok gt it?
