# FAQ: What Is Radicand In Math?

The radicand is the number found inside a radical symbol, and it’s the number you want to find the root of. It could be a square root, cube root or other root, which will be defined by the subscript found outside and just before the radical symbol.

Mathwords: Radicand. The number under the ( radical ) symbol. That is, a number which is having its square root taken (or cube root, 4th root, 5th root, nth root, etc.). For example, 3 is the radicand in.

## What is a Radicand and index?

The radicand is the number we take the root of. The index is the value of the root.

## What is the Radicand of 5?

The square root of 5 can’t be simplified father than it already is, so here is √ 5 to ten decimal places: √ 5 ≈2.2360679775

## What is this math symbol called?

Basic math symbols

Symbol Symbol Name Example
approximately equal sin(0.01) ≈ 0.01, x ≈ y means x is approximately equal to y
> strict inequality 5 > 4 5 is greater than 4
< strict inequality 4 < 5 4 is less than 5
inequality 5 ≥ 4, x ≥ y means x is greater than or equal to y

## How do you simplify a Radicand?

1. Find the largest perfect square that is a factor of the radicand.
2. Rewrite the radical as a product of the square root of 4 (found in last step) and its matching factor(2)
3. Simplify.
4. Find the largest perfect square that is a factor of the radicand (just like before)

## What is the Radicand of 3 27?

[1] For example: The cube root of – 27 is written as 3√ − 27 =− 3.

## How do you simplify?

To simplify any algebraic expression, the following are the basic rules and steps:

1. Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2. Use the exponent rule to remove grouping if the terms are containing exponents.
3. Combine the like terms by addition or subtraction.
4. Combine the constants.

## What is a positive Radicand?

The product of two numbers is positive if both numbers have the same sign as is the case with squares and square roots. a2=a⋅a=(−a)⋅(−a) A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand.

## Is 4 a perfect square?

For instance, the product of a number 2 by itself is 4. In this case, 4 is termed as a perfect square. A square of a number is denoted as n × n. Example 1.

Integer Perfect square
2 x 2 4
3 x 3 9
4 x 4 16
5 x 5 25

A radical is an expression with a square root symbol. The term under the square root symbol is called the radicand. The radicand can be either a number or a variable.

## What do indices mean?

The index of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. In this example: 82 = 8 × 8 = 64. The plural of index is indices. (Other names for index are exponent or power.)

## Can a Radicand be negative?

The radicand can be any real number (positive, negative or zero).
