The Square Roots of Negative Numbers:Like all other numbers, negative numbers have square roots. The numeric value of the square root of a negative number is the same numeric value as the square root of a positive number, but it will incorporate the term i at the end....
(15th century), and the German mathematician M. Stifel (16th century) extracted higher roots on the basis of the formula for (a + b)n.L. Euler (18th century) gave approximation methods for extracting roots that have retained their significance. Square roots of negative numbers, encountered ...
