Given the value:
-80
Determine the square root of -80
Solution:
In order to determine the square root of -80, we simply needed to enclose the value with a radical sign, or simply raised the value by ½. Hence, we must take note that negative numbers do not have a square root, as a result, it will become a complex or imaginary number, which is designated by the sign i.
= (-80)^½
= 8.9i
Final answer:
= 8.9i
