Answer:

Not sure on this but I'm pretty sure its 12i√11 since you have to use an imaginary number in order for the equation to work.

By simplifying the expression 4√−99, we have; 12i√11.

To simplify 4√−99, we first need to simplify the number present within the square root.

To do this, the factors are determined as follows;

  • 4 × √9 × √-11

We can therefore find the square root of 9 so that we have;

  • 4 × 3 × √-11.

  • 4 × 3 × √-11

  • 12 × √-11

Furthermore, √-11 can be rewritten as;

  • √-1 × √11.

However, in complex numbers, √-1 = i.

Ultimately, we have 12i√11 as the simplification of 4√−99.
