I'm terrible at logarithms ^^;;
I'd really like some help learning how to solve these kinds of equations:
8^x=4
9^x=27
I also dont get how to write logarithmic expressions as single logarithms when a problem like: log (x-1)^2-log (3x/4)^2. I dont understand what to do with the square...
I have the same problem with expanding equations with squares in them like: log base of 2 (x + 1)^2
log base of 4 r^2 t
Help would be much appreciated :]
you should look up the laws of logarithms. . x and y can be functions here. doesn't matter if they are squared or not.
another rule of logarithms is. so, etc. i put absolute values because the square would keep thing positive alwaysI have the same problem with expanding equations with squares in them like: log base of 2 (x + 1)^2
