17e^x-4=15

Question

Find the solution of the exponential equation in terms on logrithems or correct to 4 decimal places.

Answer 1

17e^x-4=15

17e^x = 15 +4 = 19

e^x = 19/17

lne^x = ln(19/17) =ln19 - ln17

xlne = ln19 - ln17                            (lne) = 1

x = ln19 - ln 17

Answer 2

l7e^x-4=15

e^x-4= 15/17

lne^x-4= ln(15/17)                   lne= 1

x-4= ln(15/17)

x= ln(15/17) + 4
