Answer 1

Ответ:

Пошаговое объяснение:

1. log12(27)+log12(64)=log12(27*64)=3
2. log9(36/4)-5= 1-5=-4
3. 3-0,27=2,73
4. 5 ^ (log5(5)+log5(4))=5^log5(20)=20
5. log50(5^3)+log50(0,4)=log50=log50(50)=1
6. log3(21a)=11, log3(3*7a)=11, Log3(3)+log3(7a)=11, 1+log3(7a)=11, log3(7a)=10
7. 3log4(a)=18, log4(a)=6. Log4(a*4^4)=log4(a)+4log4(4)= 6+4*1=10
8. 3^-log3^(-1)(4)=3^log3(4)=4. 9-4=5
9. 5+log50(5^-1)-log50(10)=5+log50(2/100)=5+log50(50^-1)=5-1=4
10. 2lod7(7)-(-log7(7))+5=2+1+5=8
