WebJun 24, 2024 · An irrational number is not equal to a rational number ; Solution :-We need to prove that 2 + √2 is not a rational number. So, Let's assume on the contradictory that 2 + √2 is a rational number . Equal 2 + √2 with p/q ( where p , q are integers , q ≠ 0 , p and q are co - primes ) So, Now, Transpose 2 to the right side . Taking LCM we ... WebFirstly: 16 = 2×2×2×2 = 2 4, and 90 = 2×3×3×5 = 2×3 2 ×5 ( 16 90) 2 = ( 24 2×32×5) 2 = ( 23 32×5) 2 = 26 34×52 But one thing becomes obvious: every exponent is an even number! So we can see that when we square a rational number, the result is made up of prime numbers whose exponents are all even numbers. Back to 2 WebRational numbers can be written in the form of a fraction (ratio) of 2 integers. The numbers that fall into this set are: -- All integers -- All fractions where the numerator and denominator are integers. -- All terminating decimals as they are just fractions in another form.
