 # Question: Is 3 A Real Number?

## Is 2/3 an irrational number?

In mathematics rational means “ratio like.” So a rational number is one that can be written as the ratio of two integers.

For example 3=3/1, −17, and 2/3 are rational numbers.

Most real numbers (points on the number-line) are irrational (not rational)..

## What Squared 0?

The square of 0 is a perfect square because the number is the product of the two equal integers 0, though, really the square doesn’t exist because 0 is nothing. … Squaring is multiplying a number by itself to get to the total. 0 multiplied by anything is 0, so 0 to 100th power is still zero.

## Which are the real numbers?

Real numbers are the numbers which include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.

## What type of number is 15 3?

Explanation: Rational numbers are defined as the quotient (division result) of two integers (whole numbers, numbers with no decimals). Therefore −153 is a rational number.
