So the opposite of squaring a number is taking its square root. For example 2 squared is written as <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=2%5E2 ALIGN=MIDDLE  ALT=\"2%5E2\"   DISABLED_style= \"max-width:90%; height:auto;\" > which equals 4. So the PRINCIPAL square root of 4 can be written as <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=sqrt%284%29 ALIGN=MIDDLE  ALT=\"sqrt%284%29\"   DISABLED_style= \"max-width:90%; height:auto;\" > which is equal to 2.\r<BR>\n" );

document.write( "Principal root means the main position root of a number. However remember that when two negative numbers are multiplied together they give a positive number. Therefore square roots of positive real numbers always have two roots: a negative and a positive. So the other root of 144 is -12. </SPAN>\n" );
