Let's solve the exponential equation 4ex = 80. (a) First, we isolate ex to get the equivalent equation Correct: Your answer is correct. . (b) Next, we take ln of each side to get the equivalent equation Incorrect: Your answer is incorrect. . (c) Now we use a calculator to find x ≈ 2.996 Correct: Your answer is correct. . (Round your answer to three decimal places.)

The solution of the exponential equation is

x = 2.996

Step-by-step explanation:

To solve the exponential equation

First, we will isolate by dividing both sides of the equation by 4, so that we get

Now, we will take the ln of both sides of the equation to get

(NOTE: )

Then,

∴ x = 2.996 (to three decimal places)

Hence, the solution of the exponential equation is

x = 2.996

astronomers is your final answer! : )

w'x is 0.

hope it
