Answer 2

Let's break down the expression step by step:

1. First, calculate the values inside the parentheses:

   • (3.2 - 1.31) = 1.89
   • (1.31 + 3.2) = 4.51
   • (2.139 - 8.75) = -6.611
   • (2.139 + 8.75) = 10.889

2. Now, perform the divisions:

   • 1.89 / 4.51 ≈ 0.4184
   • -6.611 / 10.889 ≈ -0.6071

3. Finally, multiply the results:

   • 56 * (0.4184) * (-0.6071) ≈ -14.929

So, 56⋅ (3.2 - 1.31) / (1.31 + 3.2) * (2.139 - 8.75) / (2.139 + 8.75) is approximately equal to -14.929.
