the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.
Index, radicand, and radical :) lmfao
Technically,no. A radical equation has a radical (Square root) in it, and has two solutions because the square root can be positive or negative.
radical equations have sq roots, cube roots etc. Quadratic equations have x2.
There is the Index, the coefficient and the Radican
When in doubt always square both sides of the equation.

Radical...Apex :)
An index in Algebra is the integer n in a radical defining the n-th root
Square both sides of the equation to get rid of the radical sign. Then just solve as you normally would. Good luck! :-)
They are actually to the one half power. You can take a factor in the radical and sqrt it and put in on the outside... Ex. sqrt(28) = sqrt(4 * 7) = sqrt(22 * 7) = 2sqrt(7) sqrt(28) = 2 * sqrt(7)

It often helps to isolate the radical, and then square both sides. Beware of extraneous solutions - the new equation may have solutions that are not part of the solutions of the original equation, so you definitely need to check any purported solutions with the original equation.

When arranging radicals, it is important to consider the index of the radical, whether or not the radical is mixed or entire, and then the radicand.
