1. The problem statement, all variables and given/known data 12^x=4X8^(2x) Big X= multiplication sign little x= unknown i simply cannot figure this out. Any help please? 2. Relevant equations 4.6X1.06^(2x+3)=5X3^(x)
Re: logarithms! Use logarithms! Isn't that your title? Take the log of both sides and use the rules of logarithms to simplify. What do you get?
Re: logarithms! i wouldnt post this if i could do it as easily as you said. Can you explain? Thats why i'm here.
Re: logarithms! log(12^x)=log(4*8^(2x)). That wasn't so hard. Now simplify it. Use rules of logarithms like, log(a*b)=log(a)+log(b), log(a^b)=b*log(a).
Re: logarithms! Your equation is 12^{x=(4)82x. Since you titled this "logarithms", Dick assumed you knew some basic rules of logarithms. Take the logarithm of both sides: log(12x= log((4)82x) Now use the fact that log(ab)= log(a)+ log(b) and that log(ax)= x log(a).}
