What is the true solution to 2 In e in5x = 2 In 15?
just olya [345]

Answer:

x = 3

Step-by-step explanation:

Using the rules of logarithms

ln x = ln y ⇒ x = y

ln e = 1

Given

2 ln e ln 5x = 2 ln 15 ( divide both sides by 2 )

ln e ln 5x = ln 15

ln 5x = ln 15, hence

5x = 15 ( divide both sides by 5 )

x = 3
