This question involves understanding exponents and scientific notation, and should be pretty simple once we see what's going on.
\r
\n" ); document.write( "\n" ); document.write( "To begin with, \"10%5E1\" or 10 has 2 digits
\r
\n" ); document.write( "\n" ); document.write( "\"10%5E2\" or 100 has 3 digits
\r
\n" ); document.write( "\n" ); document.write( "So it is easy to see that \"10%5E23\" has 24 digits.
\r
\n" ); document.write( "\n" ); document.write( "Now we need to look at the product of 27 and \"10%5E23\"
\r
\n" ); document.write( "\n" ); document.write( "Let's use scientific notation:
\r
\n" ); document.write( "\n" ); document.write( "27 x \"10%5E23\" is equivalent to 2.7 x \"10%5E24\"
\r
\n" ); document.write( "\n" ); document.write( "Since 2.7 x \"10%5E1\" or 27 has 2 digits,
\r
\n" ); document.write( "\n" ); document.write( "and 2.7 x \"10%5E2\" or 270 has 3 digits, we can easily surmise that
\r
\n" ); document.write( "\n" ); document.write( "2.7 x \"10%5E24\" which is equivalent to 27 x \"10%5E23\" has 25 digits!!!
\r
\n" ); document.write( "\n" ); document.write( "The answer is 25 digits. :)
\n" ); document.write( "
\n" );
