The radical of a number is the same as the root of a number, and we will learn more about the radical formula as we go along. The root can be a square root, cube root, or in general, nth root. Thus, any number or expression that uses a root is known as a radical.
An equation that is inside a radical is known as a radical equation.
An expression that lies inside a square root is known as a radical expression.
An inequation that is inside a radical is known as radical inequality.
Some examples of radicals are √7, √2y+1, etc. Let's look into the concept of radical formula followed by solved examples.
What is Radical Formula?
To solve a radical equation, it has to be made radical-free. To make an equation of nth root radical free, we power both sides of the equation with 'n'. This masked the radical equation-free from radical. Let's look into the radical formula below.
x1/n = p
(x1/n)n = pn
x = pn
The n√ symbol is known as the radical of nth root.
'n' is known as the index.
The expression or variable inside the radical symbol i.e, x is known as the radicand.
Let's take some examples to understand the radical formula.
