Verified answer
e
2-1)log2-log8+log4=0
2-1=1
Log2= 0.30
Log8= -0.90
Log4= 0.40= 0
1*0=0b

b : x− 3 y b = 2. ( x −3 + 2 ) ( x −3− 2 )
c log(x+√6)+log(x-√6)=1
log((x+√6).(x-√6)=1
log(x^2-6)=1
x^2-6=10^1
x^2=10+6
x=√16
x=4
d log^3(9)-log^3(x)=2
-log^3(x)=2-log^3(9)
-log^3(x)=2-2log^3(3)
-log^3(x)=2-2.1
-log^3(x)=0
