Question

помогите, пожалуйста!

Answer 1

log(7)x=2log(7)5+1/2*log(7)36-1/3*log(7)125
log(7)x=log(7)5²+lof(7)√36-log(7)∛125
log(7)x=log25+log6-log5
log(7)x=log(7)(25*6/5)
log(7)x=log(7)30
x=30

Answer 2

$log_7x=2log_75+frac{1}{2}log_736-frac{1}{3}log_7125\x=7^{log_75^2+log_7sqrt{36}-log_7sqrt[3]{125}}=7^{log_725+log_76-log_75}=7^{log_7(frac{25*6}{5})}=\7^{log_730}=30$
