Homework Help: log

Posted by log on Thursday, July 2, 2009 at 7:49am.

please help

given that
4^(2x+1) X 7^(x-1) = 8^x X 14^2x
evaluate 14^x

this is what i did, but i got stuck anyways.

2^(4x+2) X 7^(x-1) = 2^3x X 14^2x
2^(x+2) = 2^2x X 7^(x+1)

sorry this might be a bit confusing, but the big letter X is 'multiply'
