MATH HOMEWORK HELP, LOGS. I've got the basics done. Just don't know the Math.log :)

B = 9
Log10B = x
B = 10^x
9^1 = 10^x
Log9 = Log10^x
Log9 = xLog10
Log9/Log10 = x
Log9/1(Log10^10 = 1) = x
Log3^2 = x
2Log3 = x//

Logs aren't too hard

I know logs arent that hard, I sat in class n after the teacher showed me that u can change exponential equations like that to Logs I ripped off in an algebra way of creating my own formula, so then I wanted to be able to use that formula faster so i can do homework in 2.2 seconds every night xD. woot to epicness

4^2x+3 = 9^4x+5
Log4^2x+3 = Log9^4x+5
(2x+3)Log4 = (4x+5)Log9
(2 x Log4)x + (3 x Log4) = (4 x Log9)x + (5 x Log9)
(2 x Log4)x - (4 x Log9)x = (5 x Log9) - (3 x Log4)
((2 x Log4)-(4 x Log9))x = (5 x Log9) - (3 x Log4)
x = ( (5 x Log9) - (3 x Log4) / (2 x Log4)-(4 x Log9) )

thats how i found the formula

Nice ;P

I wonder what fun math we could do with that if we input the xyz pos of players hmm xD
