How many ordered pairs of (m,n) integers satisfy `(m)/(12)=(12)/(n)`?A. 30B. 15C. 12D. 10 |
|
Answer» Correct Answer - A `(m)/(12)=(12)/(n)` `mn=144impliesn=(144)/(3)` we want to find here total number of divisors of 144 `144=2^(4).3^(2)` Total divisors are `(4+1)(2+1)=15` But negative paris are also posible hence=30. |
