# What is a square root of 4?

What is a square root of 4?

Is √ 4 is a rational number? A rational number is any number that can be written in the form of p/q, where p and q are both integers and q≠0. Here, the given number √4 is equal to 2; the number 2 is a whole number and whole numbers are always rational. Also, it can be expressed in fraction form as 2 ⁄ 1 which means it is a rational number.

What is the square root of Root 5? The square root of 5 is 2.236.

How do you prove that Root 4 is irrational? then it is in p/q form and no factors are common. 41/2= p/q. 4Q2 =P.

## What is a square root of 4? – FAQ

### Is the number 4 irrational?

4 is not an irrational number because it can be expressed as the quotient of two integers: 4 ÷ 1.

### Is negative 4 a natural number?

Natural numbers are 1,2,3,4,.. i.e. only positive non-zero whole numbers. Whole numbers also include 0 along with natural numbers and hence −4 is neither a natural number nor a whole number.

### Why root 4 is not a irrational number?

p/q Where q is not equal to 0 And p,q are Co-Prime. Two number are Co-Prime if the only common positive integer which divides them is 1. And 2 , 1 Are co prime. hence Root 4 Is rational.

### How do you write numbers in surd form?

In general:

To simplify a surd, write the number under the root sign as the product of two factors, one of which is the largest perfect square. Note that the factor 16 is the largest perfect square. Recall that the numbers 1, 4, 9, 16, 25, 36, 49, are perfect squares.

### What is the square root of 72 simplified?

Square root of 72 in simplified form is written as 6√2.

### How do you know if a square root is fully simplified?

Simplifying a square root just means factoring out any perfect squares from the radicand, moving them to the left of the radical symbol, and leaving the other factor inside the radical symbol. If the number is a perfect square, then the radical sign will disappear once you write down its root.

### Is zero a rational number?

Why Is 0 a Rational Number? This rational expression proves that 0 is a rational number because any number can be divided by 0 and equal 0. Fraction r/s shows that when 0 is divided by a whole number, it results in infinity. Infinity is not an integer because it cannot be expressed in fraction form.
