Square Root NotationDate: 11/14/2001 at 22:44:22 From: Jacot Ramirez Subject: Square roots Where do you write the answer to a square root? Date: 11/15/2001 at 08:59:27 From: Doctor Peterson Subject: Re: Square roots Hi, Jacob. If you are simply stating the answer, you will write it as an equation, using the radical symbol merely as a notation that says you are taking the square root: ___ \/ 9 = 3 There is one way to calculate a root in which you treat the radical sign as a device for calculating similar to the long division notation: __3__4_ \/ 11 56 9 -- 6?*? 2 56 64*4 = 2 56 ---- 0 Here you write the answer above, with one digit over each pair of digits in the "radicand." But you only do this when you are using this method. You can read about this method in the Dr. Math archives: Longhand Square Roots http://mathforum.org/dr.math/problems/tim3.30.98.html - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/ |
