Yah, I meant square root(16x2) x √-1

I think that in your case the first two would be negative, making the the actual problem, split apart more like this.
Square(16) X Square(-2)=4 square(2i)
You can take the square of sixteen, 4, four but you can not get the square of a negative number like negative two.
Therefore, the only substitute would be an imaginary number, i. This number equals (square(-1))
Put in what you know
4 x square(-2)= 4 square (2i)
Take in what i just said about the imaginary number.
4square(2i) = 4square(2i)

The original problem probably asks for
sqrt(16x2)
Is that correct?
sqrt(16x2) = sqrt(16)xsqrt(2)
Does that answer the question?
