You can put this solution on YOUR website!
Thought to remember: log is another name for exponent.
\n" ); document.write( "-----------------
\n" ); document.write( "log(3)(4x-7)=2
\n" ); document.write( "Here you are told \"the log is 2\"
\n" ); document.write( "So, 4x-7 = 3^2
\n" ); document.write( "4x-7=9
\n" ); document.write( "4x=16
\n" ); document.write( "x=4
\n" ); document.write( "-------------
\n" ); document.write( "log(4)x+log(4)(x-3)=1
\n" ); document.write( "log(4)[x(x-3)]=1
\n" ); document.write( "Here you are told \"the log is 1\"
\n" ); document.write( "x(x-3)=4^1
\n" ); document.write( "solve for x
\n" ); document.write( "===============
\n" ); document.write( "3^(x+1)=27
\n" ); document.write( "Rewrite as
\n" ); document.write( "3^(x+1) = 3^3
\n" ); document.write( "x+1=3
\n" ); document.write( "x=2
\n" ); document.write( "-----------
\n" ); document.write( "4^(x-1)=64
\n" ); document.write( "Rewrite as
\n" ); document.write( "4^(x-1) = 4^3
\n" ); document.write( "x-1=3
\n" ); document.write( "x=4
\n" ); document.write( "------------
