Question

Use method of contradiction to show that √5 is irrational​

Answer 1

Answer:

lets suppose it's a rational nmbr

Therefore it cn b written in the form of p/q ...

where q is not equal to 0

:√5=p/q

(squaring both sides)

(√5)²=(p/q)²

q²=p²/√5²

since 5 divides so it shld also divide q

put p=5

q²=5²/5

q²=5m

m²=5/q²

this shows 5 divides both p nd q

nd is the factor of both

so oue supposition is wrong n it's a contradiction

hence √5 is irrational!!
