Answer 1

Answer:

hence proved please mart it as brainlist please

Step-by-step explanation:

let √5 be a rational number

we known that every rational number is in the form of a/b

√5 +√7=a/b is a rational number

√5=a/b-√7           "

√5 =a-b√7/b          "

but we known that √5 is a irrational number

so our assumpition is wrong

therefore √5 is a irrational number
