That is a number known as "i" - also known as the "imaginary unit". For more information, you may want to investigate about the so-called "complex numbers". The Wikipedia article on complex numbers may be a good starting point.

What is a root number in an equation?

The square root of a negative value is called an imaginary or number?

Yes. The letter i denotes the value of the "positive square root" of -1. So i² = -1. But also (-i)² = -1 as well. Remember that for every number there is a "positive" and "negative" square root. So if you want the square root of -4, you can do this: -4 = (-1)(4). So sqrt(-4) = sqrt[(-1)(4)] = sqrt(-1)*sqrt(4) = i*2 or -i*2. We usually write these as 2i and -2i.

What is the value of square root of 2 square root of 2 .infinite?

The value of (\sqrt{2} \times \sqrt{2}) is equal to 2, as the square root of a number multiplied by itself cancels out the square root and leaves the number. There is no concept of multiplying by infinity in this context as infinity is not a specific number but rather a concept representing unboundedness.
