the square root of -25 is the same as the square root of 25 times -1. The square root of 25 is 5, but you can't take the square root of a negative 1. The letter (i) is used to mean the square root of -1, and that is why the answer is written as 5i.

a square root is the same thing as multiplying two same numbers together. but in this case, you cant do that. since two negatives are a posative. the only two numbers that will equal -25 are -5 and 5. so the imaginary number will take the place of 5,-5. written as 5i.
