Answer 1

Answer:

Hey mate! here is ur answer hope it helps you...thank me if the answer is crct n mark me as brainliest...

Explanation:

we have to orove√5 is irrational

let us assume the opposite

√5 is rational

hence,√5 can be written in in the form a/b

where a and b( not equals to 0) are co- prime

hence,√5=a/b

√5b=a

squaring on both sides

(√5b)²=a²

5b²=a²
