the difference between a square root inside a bracket and one outside a bracket

math  drwls, Sunday, December 11, 2011 at 2:08am
If a number is outside the bracket, its square root is not taken.
If you are refering to the small superscript number in front of a radical sign, that indicates a root that is not the square root. 3 in front of a radical sign means cube root, for example.
