    Question

    When 5 1850  is divided by 126, the remainder

    is:
    A 89 Correct Answer Incorrect Answer
    B 01 Correct Answer Incorrect Answer
    C 101 Correct Answer Incorrect Answer
    D 25 Correct Answer Incorrect Answer

    Solution

    5 1850  = [(5 3 ) 616  * 5 2 ] = [125 616  * 25]
    When (125 616  * 25) is divided by 126,
    => [125 616  * 25]/126
    => [(-1) 616  * 25]/126 [When power on -1 is even, then -1 is positive]
    So, remainder = 1 * 25 = 25
