Full solution

Q. Evaluate ab−0.5bab - 0.5b when a=1a=1 and b=5b=5.
  1. Substitute Values: Substitute the given values of aa and bb into the expression.\newlineThe expression is ab−0.5bab - 0.5b. We are given that a=1a = 1 and b=5b = 5. Let's substitute these values into the expression.\newline1×5−0.5×51 \times 5 - 0.5 \times 5
  2. Perform Multiplication: Perform the multiplication.\newlineNow we multiply the numbers.\newline(1×5)−(0.5×5)=5−2.5(1 \times 5) - (0.5 \times 5) = 5 - 2.5
  3. Subtract Terms: Subtract the second term from the first term.\newlineAfter multiplication, we subtract 2.52.5 from 55.\newline5−2.5=2.55 - 2.5 = 2.5
