Question

Помогите,пожалуйста,буду признателен.

Answer 1

$log_{sqrt{3}} frac{1}{3}-log_{0.2}5+log_{64}4=-2+1+frac{1}{3}=-frac{2}{3}$

$3^{log_{2}frac{1}{4}+log_{3}5}=3^{log_{2}frac{1}{4}}cdot3^{log_{3}5}=3^{-2}cdot5=frac{1}{9}cdot5=frac{5}{9}$

$7^{log_{7}2} :log_3frac{1}{9}=2:(-2)=-1$

$11^{log_{11sqrt{11}}125-log_{121}9}=11^{frac{2}{3}log_{11}5^3-log_{11}3}=11^{log_{11}25-log_{11}3}=11^{log_{11}25}:11^{log_{11}3}=frac{25}{3}=8frac{1}{3}$
