Answer» Correct Answer - Option 4 : All statements are correct Given: The given expression is (7xy/z – 3yx/z + 2yxz-1) Concept Used: Concept of divisibility Calculation: The given expression can be written as (7xy/z – 3yx/z + 2yxz-1) = (7xy/z – 3yx/z + 2yx/z) = (7xy/z –yx/z) = (6xy/z) Now, the whole term is multiple of 6 ∴ (6xy/z) is divisible by 2, 3 and 6 Hence, option (4) is correct |
