Question

Check whether following statement is true or false.

$7\sqrt{5}$ is a rational number.

• A. True
• B. False

Answer 1

The correct option is B False

An irrational number is any real number that cannot be expressed as a ratio a/b, where a and b are integers and b is non-zero.
$7\sqrt{5}$ is irrational as it can never be expressed in the form a/b
