# What is the simplest form of the radical expression, and what can it be? ## What is a simpler version of the radical expressions?

Expressing in the simplest radical form simply means to simplify a radical so there are no square roots, cube root, or 4th roots left. This also refers to removing radicals from the fraction’s denominator.

### What is radical 6 simplified?

6=2. 449 Thus, this is the simplified version of the square root of 6.

#### What is a fully simplified radical expression?

An expression can be simplified if it does not contain a radical sign. We must rationalize the denominator in case we have a radical sign. This is done by multiplying the numerator AND denominator by adding the radical in denominator.

How do you know when a radical expression is in simplest form?

Description – Simplifying Radical Expressions A radicand is defined as a square that contains one perfect square. It cannot contain a factor greater than 1. 2. The radical sign is the only fraction.

What is the number under the radical called?

used for indicating a root is known as a radical. It is also called “x radical” or “the next root of x”. The horizontal line in the radical symbol is called “the vinculum”, the quantity below the vinculum is “the radicand,” and the quantity “n” written to the left is “the index.”

## What are the different parts of a radical expression?

The radical expression ab has three main features: the radical symbol (it looks almost like a checkmark), the index (the small number that is tucked away from the radical symbol), as well as the radicand (the quantity written below the horizontal bar of a radical symbol).

### What does the number in front of a radical mean?

This means that you now consider the “nth root” of a instead of the “square root”. This is equivalent to writing a1n. The square root can be “undone” simply by applying a squared word, i.e. (a)2=a), and the nth root can be “undone” by applying the power (i.e. (na)n=a).
