How do you prove ✓ 7 ✓ 5 is irrational?

Rational numbers are terminating decimals but irrational numbers are non-terminating.
  1. Let us assume that 7 √ 5 is a rational number.
  2. Hence, 7 √ 5 can be written in the form of a b where a , b are co-prime and b not equal to 0 .
  3. 7 √ 5 = a b.
  4. √ 5 = a 7 b.
  5. Here, √ 5 is irrational and a 7 b is a rational number.
