Roots are written using a radical sign, and a number denoting
which root to solve for. When none is given, it is an implied
square root.  Key Points    • Roots are usually written using
the radical symbol, but can also be written by raising the
number to a fraction. Then, the root is the inverse of the
raised power. Like this:<equation contenteditable="false">$\sqrt
x = x^{\frac12}$.    • To solve an equation with a radical:
isolate the radical on one side of the equation, get rid of your
radical, solve the remaining equation.    • To eliminate a
square root, square the radical, to eliminate a cubed root, cube
the radical - don't forget to do the exact same thing to the
other side of the equation!     • A root (of a number or
quantity).     1. fig. 2     Properties of Equality      Make
sure to use these properties when solving an equation.  Roots
are written using a radical sign. If there is no denotation, it
is implied that you are finding the square root. Otherwise, a
number will appear denoting which root
