Answer:
In Direct Proof
Explanation:
Direct Proof is one of the methods, used to prove in maths
Such conclusion is established by logically combining the axioms, definitions & earlier theorems.
Example : To prove - Sum of two even integers is always even
Let a , b be two even integers. If they are even, they can be written as a factor of 2, as a = 2x & b = 2y respectively. Their sum a + b = 2x + 2y = 2 (x+y). So, their sum is also even, as it has a factor of 2. The statement is hence proved by direct method.
