Question

2+√6 is rational number prove

​

Answer 1

Answer:

By definition, that means there are two integers a and b with no common divisors where: Now this is the contradiction: if a is even and b is even, then they have a common divisor (2). Then our initial assumption must be false, so the square root of 6 cannot be rational

Answer 2

Answer:

2+✓6is not a rational number

Step-by-step explanation:

By definition, that means there are two integers a and b with no common divisors where: ... Now this is the contradiction: if a is even and b is even, then they have a common divisor (2). Then our initial assumption must be false, so the square root of 6 cannot be rational.
