I need help making ln2x+3(lnx-lny) a single logarithm
Hi bastropgarl,
1) $\displaystyle \log_{a}{\left(b.c\right)}\;=\;log_{a}{b}+log_{a}{ c}$
2) $\displaystyle log_{a}{\left(\frac{x}{y}\right)}\;=\;log_{a}{x}-log_{a}{y}$
3) $\displaystyle x\log_{a}{y}\;=\;\log_{a}{y^x}$
Try to use these rules. If you still can not solve, write again.
