solve for x 3^(x-7)=14^(2x) write the exact answer using base-10 logarithms


%0D%0A3%5E%28x-7%29=14%5E%282x%29%0D%0A 

%0D%0Alog%283%5E%28x-7%29%29=log%2814%5E%282x%29%29%0D%0A 


%0D%0A%28x-7%29%2Alog%283%29=2x%2Alog%2814%29%0D%0A 

x%282log%2814%29-log%283%29%29=-7log%283%29 
x=-7log%283%29%2F%282log%2814%29-log%283%29%29
