The real fourth roots are -0.3 and 0.3
-0.07 and +0.07
It is 15, -15.
They are 0.5 : it is a triple root.
No. The square roots 8 are irrational, as are the square roots of most even numbers.
A real root is when a quadratic equation, or the graph of a polynomial, crosses the x axis, or when the y coordinate is equal to 0. On any polynomial to the degree of two, when graphed the line follows a smooth arc in the shape of a "U" or and upside down "U". Since there are only two prongs to the parabola, or arc, it can only cross the x axis twice, if at all. So there can only be 2 real roots.
Upto 4. If the coefficients are all real, then it can have only 0, 2 or 4 real roots.
The 4th root of 256 is 4
