Question

Tolong bantu ya gan makasi

Answer 1

log x = -2
x = 1/100
log x = 1
x =10
jadi (1/100,10) D

Answer 2

Log^2 x + log x =log 100
log^2 x + log x =2
misal log x = p
mka p^2 + p =2
p^2 + p-2=0
(p+2)(p-1)=0
p= -2 p= 1

log x=p
log x=-2
x=10^-2
x=1/100

log x=p
log x=1
x=10


maka jawabnya: D
