Answer 2

Answer:

Option D is correct, i.e. 6i√2

Step-by-step explanation:

Simplify the square root of negative 72.

We know the square root of negative numbers are called Imaginary numbers and are denoted by √(-1) = i.

Similarly the square root of negative 72 can be simplified as below:-

√(-72)

= √(-1*72)

= √(-1) * √72

= i * √72

= i * √(6*6*2)

= i * 6√2

= 6i√2

Hence, option D is correct, i.e. 6i√2
