\"4%5E%28x+%2B+1%29+-+7+=+14\"
\n" ); document.write( "\"4%5E%28x+%2B+1%29+=+14+%2B+7\"
\n" ); document.write( "\"4%5E%28x+%2B+1%29+=+21\" -------- Exponential form
\n" ); document.write( "\"log+%284%2C+21%29+=+x+%2B+1\" ------ Logarithmic form
\n" ); document.write( "\"x+%2B+1+=+log%2821%29%2Flog%284%29\" ------- Applying change of base
