Ребятушки! Help me!!!
Очень нужно!!!

Answer 1

Ответ:

1)27

2)x= [13/4; +inf)

3)8 + 3log18(2)

Пошаговое объяснение:

1) ( 9^log3(9) ) / 9^log9(3)= 81 / 3 =27

9^log3(9) = 3^2log3(9) = 81

9^log9(3) = 3

2)2-log0.5(x-3)=>0

log0.5(x-3)<=2

x-3=>0.5^2

x=>13/4

x= [13/4; +inf)

3)27^log3(2) + log18(2) + 2log18(2) = 8 + 3log18(2)

27^log3(2) = 3^3log3(2) = 8

log18(2) + 2log18(2) = 3log18(2)
