Question

solving exponential logarithmic equations.. I need help with this one..please see attachment..

Answer 1

correct

Answer 2

Alright, so in order to get rid of a "e" you have to talk the natural log of (just like adding is the opposite of subtracting). so you take the natural log of "e" and the exponents come down. adding 5 to the other side makes it easier. after taking the ln its just simple math

Answer 3

lne = 1 thats how lne disappeared

Answer 4

sorry dont get it i have 2x-3=ln5????

Answer 5

lne(2x-3)=ln(5)
= 2x(lne) - (3lne)=ln(5)
= 2x(1)-3(1)=ln(5)
=2x-3=ln(5)
