Homework Statement
Solve Algebraically:
Log(subscript4) (a^2 + 2) = Log(subscript 4) (2a + 10)
Homework Equations
other equations that are similar which I can't do are:
Solve Algebraically:
-Log(subscript 5) (x + 3) + Log(subscript 5) (x - 2) = Log(subscript 5) 14
-Log(subscript 2) (2x + 6) - Log(subscript 2) x = 3
The Attempt at a Solution
not sure if this is right but I think you would divide by Log(subscript 4)
Log(subscript4) (a^2 + 2) = Log(subscript 4) (2a + 10)
------------------------------------------------------
Log(subscript4) Log(subscript4)
canceled those out leaving:
a^2 + 2 = 2a + 10
expand the equation:
this is where i get lost, unless I am doing it completely wrong. Please help.
