What is a multiplication? A quick addition:
\n" ); document.write( "3+3+3+3+3= 15 Instead of adding 3 five times we can:
\n" ); document.write( "3*5=15 and we have replaced four operations with one.
\n" ); document.write( "The opposite of multiplication is division.
\n" ); document.write( "--------------------
\n" ); document.write( "And what is an exponent? A quick multiplication:
\n" ); document.write( "3*3*3*3*3= 243 Instead of multiplying 3 five times we can:
\n" ); document.write( "3^5
\n" ); document.write( "The opposite of an exponent is a root
\n" ); document.write( "-------------------------------------
\n" ); document.write( "The area of the square is S^2 or what is the same S*S. So we have to undo the square. Since it's S^2 we need the square root:
\n" ); document.write( "sqrt125= 11.18 is the length of each side.
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Check: 11.18*11.18= 125 We have the correct answer \n" ); document.write( "

\n" );
