You can put this solution on YOUR website!
log2 8 = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this is equivalent to asking \"what power of 2 is needed to equal 8\"? Answer is 3, since $\"2%5E3\"$ is 2*2*2 which is 8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You need to become familiar with this form of question rather than having it written as $\"2%5Ex+=+8\"$ . They are 2 opposite forms of the same problem just like 3-x=7 is just the same as asking x=3-7.\r
