**Reiny**, Wednesday, October 31, 2012 at 4:07pmDo you want the actual algorithm to find the square root by hand ?

Here is a good expanation and example to follow.

http://www.homeschoolmath.net/teaching/square-root-algorithm.php

To find the cube root of a number is a bit more complicated and in our days is considered impractical, but here is a method explained. Look at the 2nd example scrolling down about 1/3 of the page

http://mathforum.org/library/drmath/view/52605.html

If you want to know the concept of square roots and cube roots ?

the square root of a number is that number which when multiplied by itself two times gives us that number

e.g.

√64 = x , so that (x)(x) = 64

and from our multiplication table we know that

(8)(8) = 64 , so that

√64 = 8

the cube root of a number is that number which when multiplied by itself three times gives us that number

e.g.

∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64

so ∛64 = 4 - math -
