Question

Is 2n is an irrational number? Why?​

Answer 1

Answer:

A proof that the square root of 2 is irrational. Let's suppose √2 is a rational number. Then we can write it √2 = a/b where a, b are whole numbers, b not zero. We additionally assume that this a/b is simplified to lowest terms, since that can obviously be done with any fraction.

Answer 2

2 is not an irrational number.

Step-by-step explanation:

• A number is said to be rational if it can be expressed in terms of quotient of two integers.

• Rational number can be expressed as a/b, where both a and b are integers and b does not equal zero.

• The number 2 can be represented as  $\frac{2}{1}$   also 2 and  1 are integers and the denominator is not zero.

• This agrees with the condition for a number to be rational number.

• Thus 2 is an rational number.

• Some examples of irrational number are 3.14, 5.4,0.234 etc
