Ex 1.3, 2 Verify that a ÷ (b + c) ≠ (a ÷ b) + (a ÷c) for each of the following values of a, b and c. (b) a = (–10), b = 1, c = 1a ÷ (b + c) = (−10) ÷ (1 + 1) = (−10) ÷ 2 = (−10)/2 = −5 (a ÷ b) + (a ÷ c) = [(−10) ÷ 1] + [(−10) ÷ 1] = (−10) + (−10) = −10 − 10 = −(10 + 10) = −20 ∴ LHS ≠ RHS Hence verified
