Answer:

Step-by-step explanation:

Root 5 is rational let us assume that

Root 5 = a/b

Where a and b are coprimes

Root 5a=b

Square on both sides

,5a2=b2

A2 divides B2

Therefore a also divides b

5a2=c2

C2 divides a2

Therefore c divides a

Therefore our assumption is wrong

It is an irrational number.
