Question

me ajuda gnt , coloquem calculos pfv

Answer 1

Uma solução:

3)
$log_{\frac{1}{125}}{5.\sqrt[3]{5} }=x\\\\ (\frac{1}{125})^x=5.\sqrt[3]{5}\\ (5^{-3})^x=5.5^{\frac{1}{3}}\\ 5^{-3x}=5^{1+\frac{1}{3}}\\ 5^{-3x}=5^{\frac{4}{3}}\\ -3x=\frac{4}{3}\\ x=\frac{\frac{4}{3}}{-3}\\ x=\frac{4}{3}.\frac{-1}{3}\\ x=\frac{-4}{9}$

4)
$log_232+log_{0,5}{\frac{1}{8}}\\ log_232+log_{\frac{1}{2}}{\frac{1}{8}}\\ 5+3=8$
