Answer:The principal square root is the positive number square root. Unless otherwise stated, "the square root" of a number refers ONLY to the principal square root. The square root of n2 is the absolute value of n. When solving a simple equation such as x2 = 25, it must be observed that there are two solutions.

Answer:
Real solutions: none
Complex principal solution: 50i
Step-by-step explanation:
sqrt (-2500)
If we are working with only real numbers, then there is no solution since it is a negative number and negative numbers have to square root in the real domain
If we are in the complex realm
sqrt(-2500) = sqrt(-1) sqrt(2500)
= i (50)
We only took the positive values since we are taking the principal square root
= 50i
