Why am I allowed to remove $\ln$ from both sides of an equation?
Mar 17, 2019 · When I have this equation: $\ln (x+2) = \ln (x^2)$, why can I just remove the $\ln$ from both sides by raising it to the power of e. Does this not permanently change what the equitation equals?
How is log base 10 related to the Natural Logarithm
May 23, 2019 · This can similarly be expressed as ln7 divided by ln4, using the natural logarithm. Using the above example, Why is it that these two ratios are equal, but log base 10 (7) is not equal to ln 7? …
sequences and series - Show that $\ln n \lt 1+\frac {1} {2}+\cdots+ ...
Dec 18, 2025 · Now I know that $$\ln (1+n)<n\ \text {for}\ n\gt0$$ which implies that $$\ln n \lt n-1$$ Therefore every term in the series on the left must be less than its corresponding term in the …
How to show that $n^ {\ln (\ln (n))} = \ln (n)^ {\ln (n)}$
Mar 6, 2016 · $$\ln \left (n^ {\ln\left (\ln (n)\right)}\right) = \ln \left ( \ln (n)^ {\ln (n)}\right)$$ Recall that $\log_b a^c = c\log_b a$. Use this property on both sides: $$\left (\ln\left (\ln (n)\right)\right)\left (\ln …

Show that $\ln (a+b) =\ ln (a) + \ln (b)$ when $a = \frac {b} {b-1}$
The original question in my textbook asked if the equality $\ln (a+b) = \ln (a) + \ln (b)$ was true. My initial answer was that it was not true, but I missed this special case, which I think was very hard to "see".
