Question

What is the difference between a "root" and a "square root"?

Answer 1

A root is one of one or several answers in most quadratic equations.

Vieta's theorem - X1+X2=-b/a, X1 x X2=c/a

X1 and X2 are roots, or answers of the equation.

A square root is part of radical and exponential equations - sqrt(16) = 4.

Answer 2

Under root can be used for nth root, however, square root can only be used for 2nd root. All square roots are under roots, but all under roots are not sqaure roots. ... However, under root of 729 to the power 3 cannot be written as square root of 729.
