imaginary numbers occur in the quadratic formula because of the radical symbol, and the possibility of a negative radican and that results in imaginary numbers. I hope this helped!
-The radical is the symbol that represents a square root. -The radicand is the number underneath the radical symbol. -The coefficient is the number out in front of the radical. (We assume that the coefficient multiplies the radical, the same way it would multiply with a variable.)
No. Radical(1.21) = 1.1, for example, is rational.
The term radicand means the number or expression inside the radical symbol. For example, when we have the square root of 2, the 2 is inside the radical symbol. It is the radicand. The radicand may be a number or an algebraic expression. Also, there is not limit to the number of terms the radicand may contain. It may even be infinite!
The radical symbol ( âˆš ) followed by a line above what's in the radical, designates positive square root.
OH is not a chemical symbol of an element: it is the chemical formula of the ion hydroxyl (anion OH-) or of the radical OH.
If the symbol preceding the 61 is intended to be a radical sign, the answer is yes. If it is not a radical, it depends on the value of v.
