Q. What is the sign of a⋅(−bb) a \cdot\left(\frac{-b}{b}\right) when a=0 a=0 and b<0 b<0 ?\newlineChoose 11 answer:\newline(A) Positive\newline(B) Negative\newline(c) Zero
  1. Substitute given values: First, let's substitute the given values into the expression. \newlinea⋅(−bb)a\cdot\left(\frac{-b}{b}\right) becomes 0⋅(−bb)0\cdot\left(\frac{-b}{b}\right).
  2. Simplify expression inside parentheses: Now, simplify the expression inside the parentheses. (−b)/(b)(-b)/(b) is −1-1 because b/bb/b is 11 and the negative sign makes it −1-1.
  3. Multiply to get result: Next, multiply 00 by −1-1. 0×−10 \times -1 equals 00.
  4. Final answer: Since any number multiplied by 00 is 00, the sign of the expression is zero.\newlineSo, the answer is (C) Zero.
