Answer:

x = (1/2)(ln 3)

Explanation:

Please indicate exponentiation using the symbol " ^ ":

5e^(2x) - 4 = 11

To solve this, add 4 to both sides, obtaining: 5e^(2x) = 15

Next, divide both sides by 5, obtaining e^(2x) = 3

Now take the natural logarithm (ln) of both sides:

2x = ln 3

Finally, divide both sides by 2, obtaining: x = (1/2)(ln 3)

This last result is approx. equal to 0.549
