Question

Hitunglah nilai setiap bentuk:
a. log 10^4
b. ^5 log 125
c. ^3 log 1/27
d. ^2 log 0, 25
tolong yaa :))

Answer 1

A. log 10^4 = 4 . log 10
= 4 . 1 = 4
b. ^5log 125 = 3
c. ^3log 1/27 =^3log 3^-3
= -3 . ^3log 3
= -3 . 1 = -3
d. ^2log 0.25 = ^2log 1/4
= ^2log 2^-2
=-2 . ^2log 2
= -2 . 1 = -2

Answer 2

A. log 10^4=4
b. 5log125=5log 5^3=3
c. 3log1/27=3log 3^(-3)=-3
d. 2log 0,25=2log 5^2-2log10^2=2 [2log 5 - 2log 10]= -2
