Here are the solutions to the questions: Question 11: Use logarithms table to evaluate: (0.7214 × 20.37)/(608) Step 1: Let N = (0.7214 × 20.37)/(608). Take the logarithm of both sides. N = (0.7214) + (20.37) - (608) Step 2: Find the logarithms of each number using logarithm tables. (0.7214) = 1.8582 (20.37) = 1.3090 (608) = 2.7839 Step 3: Perform the addition and subtraction of the logarithms. N = 1.8582 + 1.3090 - 2.7839 First, add the positive logarithms: 1.8582 + 1.3090 = (-1 + 0.8582) + (1 + 0.3090) = 0.8582 + 0.3090 = 1.1672 Now, subtract the logarithm of the denominator: N = 1.1672 - 2.7839 N = -1.6167 Step 4: Convert the negative logarithm to the standard characteristic-mantissa form. -1.6167 = -2 + 0.3833 = 2.3833 Step 5: Find
