$e^{3x}+16=8\ \ \ |-16\\\\e^{3x}=-8\ \ \ FALSE\\\\x\in\O\ \ \ /no\ solution/$

$If\ e^{3x+16}=8\ \ \ \ |\ln\\\\\ln e^{3x+16}=\ln8\\\\(3x+16)\ln e=\ln8\\\\3x+16=\ln8\ \ \ |-16\\\\3x=\ln8-16\ \ \ |:3\\\\x=\dfrac{\ln8-16}{3}$

What is log(z^4/5) written in expanded form?

Ostrovityanka [42]

To get answer:

$\mathrm{Apply\:log\:rule}:\quad \log _c\left(\frac{a}{b}\right)=\log _c\left(a\right)-\log _c\left(b\right)\\\log _{10}\left(\frac{z^4}{5}\right)=\log _{10}\left(z^4\right)-\log _{10}\left(5\right)\\=\log _{10}\left(z^4\right)-\log _{10}\left(5\right)\\\mathrm{Simplify}\:\log _{10}\left(z^4\right)\\\log _{10}\left(z^4\right)\\\mathrm{Apply\:log\:rule\:}\log _a\left(x^b\right)=b\cdot \log _a\left(x\right),\:\quad \mathrm{\:assuming\:}x\:\ge \:0\\=4\log _{10}\left(z\right)\\$

Answer: $4\log _{10}\left(z\right)-\log _{10}\left(5\right)$
