Question

PROVE THAT 7-2ROOT3 IS A IRRATIONAL​

Answer 1

Explanation:

This will give rise to 2 unique integers a and b such that, 7+2 under root 3, where a and b are co primes and b is not equal to 0. Here, as b, a, 7 and 2 are all integers, a+7b÷2b is real. ... Therefore, 7+2 under root 3 is an irrational no. Hence proved.

Answer 2

Explanation:

This will give rise to 2 unique integers a and b such that, 7+2 under root 3, where a and b are co primes and b is not equal to 0. Here, as b, a, 7 and 2 are all integers, a+7b÷2b is real. ... Therefore, 7+2 under root 3 is an irrational no. Hence proved.
