You can put this solution on YOUR website!
log2 (1/16) = y
\n" ); document.write( "Write the exponent equiv of logs
\n" ); document.write( " $\"2%5Ey+=+%281%2F16%29\"$
\n" ); document.write( "We know that 2^-1 = 1/2 and that 1/16 = 1/2 * 1/2 * 1/2 * 1/2
\n" ); document.write( "therefore
\n" ); document.write( "y = -4
\n" ); document.write( " $\"2%5E%28-4%29+=+%281%2F16%29\"$
\n" ); document.write( " \n" ); document.write( "
