You can put this solution on YOUR website!
If v=log(base 2)(1/4), by definition of log,
\n" ); document.write( " 2^v = 4.
\n" ); document.write( " Now if v= -2, 2^(-2) = 1/2^2 = 1/4
\n" ); document.write( " So your answer is correct.\r
\n" ); document.write( "\n" ); document.write( " One way to solve:
\n" ); document.write( " v = log(base 2)(1/4) = -log(base 2)4 = -log(base 2) 2^2
\n" ); document.write( " = - 2 log(base 2) 2 = -2 * 1 = -2.\r
\n" ); document.write( "\n" ); document.write( "
