How do i go about solving questions such as
\n" ); document.write( "----------------
\n" ); document.write( "4x^2/3= 18
\n" ); document.write( " $\"x%5E%282%2F3%29+=+4.5\"$
\n" ); document.write( "Cube both sides
\n" ); document.write( " $\"x%5E2+=+4.5%5E3\"$
\n" ); document.write( "x = ą sqrt(4.5^3) = ąsqrt(91.125)
\n" ); document.write( "x =~ ą 9.5459
\n" ); document.write( "----------------
\n" ); document.write( "Take the log of both sides
\n" ); document.write( "3^x=75
\n" ); document.write( "xlog(3) = log(75)
\n" ); document.write( "x = log(75)/log(3)
\n" ); document.write( "x =~ 3.929947
\n" ); document.write( " \n" ); document.write( "
