-79 -68 21 46
-48 -21 27 54
-68 -13 4 32
Answer:
±3i
Step-by-step explanation:
Given the value ±√-9, we are to express the value using the imaginary number 'I'
±√-9 = ±√9×-1
= ±√9 × √-1
In complex number, √-1 = i
The expression becomes;
±√9 = ±3 × i
±√9 = ±3i
Hence the value in simplified form is ±3i
