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.
The index in a radical indicates the degree of the root being taken. For example, in the radical expression (\sqrt[n]{a}), (n) is the index, which specifies that you are finding the (n)th root of (a). If the index is not written explicitly, as in (\sqrt{a}), it is understood to be 2, indicating a square root. The index helps determine how many times the number must be multiplied by itself to achieve the value under the radical.
An equation that contains a radical with a variable in the radicand is called a radical equation. These equations typically involve square roots, cube roots, or higher roots, and the variable is located inside the radical symbol. Solving radical equations often requires isolating the radical and then raising both sides of the equation to an appropriate power to eliminate the radical.
To solve a radical equation, isolate the radical on one side of the equation and then square both sides to eliminate the radical. After squaring, simplify the resulting equation and solve for the variable. Finally, check all potential solutions by substituting them back into the original equation to identify any extraneous roots, which are solutions that do not satisfy the original equation.

An index in Algebra is the integer n in a radical defining the n-th root
In a radical expression, the index is a number that indicates the degree of the root being taken. It is typically found as a small number positioned to the upper left of the radical symbol. For example, in the expression ( \sqrt[3]{x} ), the index is 3, indicating the cube root of ( x ). If no index is written, it is assumed to be 2, representing the square 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)
radical equations have sq roots, cube roots etc. Quadratic equations have x2.
