WebSo the right-hand side simplifies to log base 10 of 8. The left-hand side is log base 10 of 3x. So if 10 to some power is going to be equal to 3x. And 10 to the same power is going to be equal to 8. So 3x must be equal to 8. 3x is equal to 8, and then we can divide both sides by 3. Divide both sides by 3, you get x is equal to 8 over 3.

Web9 Jan 2024 · This is Euler's Formula, one of the most famous mathematical formula in history. Suddenly e z being a negative number is not impossible. But if e z is negative then we need to have e z = e a + b i = e a ( cos b + i sin b) so cos b + i sin b is a negative number. That means b = π . So z = i π. So this means ln − 1 ∗ x = ln − 1 + ln x = i π + ln x. WebAnd I don't get why you can log both sides.
