Question

29. The number of solution of log4(x-1) = log2(x-3) is
a. 3
b. 1
c. 2
d. 0​

Answer 1

Answer:

1

Step-by-step explanation:

log4(x-1)=log2(x-3)

log4 + log(x-1)=log2+log(x-3)

2log2+log(x-1)=log2+log(x-3)

log2=log(x-3)-log(x-1)

log2=log(x-3/x-1)

or...(x-3)/(x-1)=2

:::x=-1 is the only one solution.
