If a x b 0 then either a 0 or b 0
WebEither ∣a∣ = 0 or ∣b∣ = 0. Solution: Given that, a ⋅b = 0. Then, either ∣a∣ = 0 or ∣b∣ = 0 or a ⊥ b (in case a and b are non-zero) and if a× b = 0 then either ∣a∣ = 0 or ∣b∣ = 0 or a∥b (in … WebWe shall define " a is greater than b " to mean: a − b is positive. Algebraically: a > b if and only if a − b > 0. On the basis of this definition, we can prove various theorems about inequalities. Theorem 1. We may add the same number to both sides of an inequality, and the sense will not change.

Webneither a = 0 nor b = 0 Easy Solution Verified by Toppr Correct option is C) For product of a & b to be zero atleast one of them should be zero, otherwise two non zero numbers … WebYou can do this by considering four possible cases when neither a nor b equals 0. For example, one case would be a and b are both positive. In that case, we know ab > 0, and so certainly ab in not 0. Prove: If ab = 0, then either a = 0 or b = 0. Hint: Use an indirect proof.
Web17 apr. 2024 · In particular, let A and B be subsets of some universal set. Theorem 5.2 states that A = B if and only if A ⊆ B and B ⊆ A. In Preview Activity 5.2.2, we created a Venn diagram that indicated that A − (A − B) = A ∩ B. Following is a proof of this result. Notice where the choose-an-element method is used in each case.

So, the formula holds for a >= 0. If a < b, then 0 < b -a. By definition, max (a, b) = a. If 0 < b -a, then the formula is max (a, b) = 1/2 (a + b + b - a) = b. So, the formula holds if a < b.
