Based on the definition of logarithmic and exponential functions we write:\r
\n" ); document.write( "\n" ); document.write( " $\"log%284%2C+64%5Ex%29=y\"$ => $\"4%5Ey=64%5Ex\"$ => $\"4%5Ey=4%5E%283x%29\"$ => $\"y=3x\"$ .\r
\n" ); document.write( "\n" ); document.write( "Answer: $\"log%284%2C+64%5Ex%29\"$ , is equivalent to 3x. \n" ); document.write( "
