Answer:
[tex] \sqrt{ab} [/tex]
Step-by-step explanation:
Given that both a and b are non-negative numbers, [tex] \sqrt{a} \cdot \sqrt{b} = \sqrt{ab} [/tex] .
Please keep in mind that this DOES NOT applies to negative numbers.
If a and b can be any integers (one of them is negative or both of them):
a = b = -1,
[tex] \sqrt{-1} \cdot \sqrt{-1} = \sqrt{-1^2} =1[/tex]
The equation above is false.
Complex number i = ✓(-1)
i² = -1 NOT i² = 1
