Solve the following logarithmic equation.?
log4 (x+3) - log4 (x) = log4 (3)
Round off answer to 4 decimal places.
The 4's by "log" are supposed to be down and small. Like x^2 but the opposite. Hope that makes sense.

"The 4's by "log" are supposed to be down and small"
They are the base of the logarithms.
log₄(x + 3) - log₄(x) = log₄(3)
log₄((x + 3)/x) = log₄(3)
(x + 3)/x = 3
x + 3 = 3x
x = 1.5
