Answer: No Solution
Explanation:
ln (x + 5) - ln (x - 5) = 4 restrictions: x + 5 > 0 and x - 5 > 0 --> x > 5
= 4
= e⁴
x + 5 = e⁴ (x - 5)
x + 5 = 54.5982(x - 5)
x + 5 = 54.5982x - 272.99075
-53.5982x = -277.99075

x = 4.999995
rounded to the nearest 4 decimal places: x = 5
5 is not greater than 5 so it is not valid

Answer: -1.3322
Explanation:
224 eˣ⁻² = 8
eˣ⁻² =

eˣ⁻² =

ln eˣ⁻² =

x - 2 =

+2 +2
x =
+ 2
x = -3.3322 + 2
x = -1.3322
