If you have a data set, simply take the square root of the sum of the squares of the data points. Let's say you have three numbers a, b, and c. RSS = SQRT(a2 + b2 + c2).

to find the root-sum square of n numbers you square each number, add them, then take square root of sum
For exanple root sum square of 2,3, and 4 is square root of (4+9+16) = sqrt(29) = 5.39
The length of the hypotenuse is equal to the root of the sum of the squares of the other two sides.
Concerning right triangles: "A" squared, plus "B" squared, equals "C" squared. Just square your "known measurements", and add them together. Then find the square root of the sum you've found.
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
The diagonal of a square whose area is 36 is the square root of 72, or about 8.49. Since the area of a square is side(squared), then the sides are each 6. Then since a(squared) + b(squared) = c(squared), for a triangle (the diagonal), you get the square root of 72.
From point A to point B You need the X and Y value of both point A and B Formula = Distance = Square root of [(x1 + x2)2 + (y1 + y2)2] So therefore given points (1:2) and (5:-6) Square root of (1 - 5)squared + (2 + 6)squared =Square root of -4 squared + 8 squared =Square root of 16 + 64 =Square root of 80 This can be your answer but you should go a step further =Square root of 80 =Square root of 16 * 5 =4*Square root of 5
