Assertion : 78 ፥ 74 = 74
Reason : If a > 0 be a real number and p and q be rational numbers. Then ap x aq = ap + q.
DIRECTION : In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion : √5 is an irrational number.
Reason : A number is called irrational, if it cannot be written in the form p/q, where p and q are integers and q ≠ 0.
