Question

6,56×4,36-3,36(0,736+2,464)-20,0424(32,24×0,32+366,032×0,4):2,3×18,6388

Answer 1

0,736+2,464=3,2*3,36=10,752
6,56*4,36=28,5144-10,752=17,7624-20,0424=-2,1928
32,24*0,32=10,3168+146,4128=156,7296:2,3*18,6388=1270,1094210783

Answer 2

To solve the given expression:

6.56 × 4.36 - 3.36(0.736 + 2.464) - 20.0424(32.24 × 0.32 + 366.032 × 0.4) ÷ 2.3 × 18.6388

Let's break it down step by step:

Step 1: Calculate the expressions within parentheses:

0.736 + 2.464 = 3.2

32.24 × 0.32 + 366.032 × 0.4 = 10.3168 + 146.4128 = 156.7296

Step 2: Substitute the calculated values back into the expression:

6.56 × 4.36 - 3.36(3.2) - 20.0424(156.7296) ÷ 2.3 × 18.6388

Step 3: Calculate the multiplication and division operations:

6.56 × 4.36 = 28.5056

3.36(3.2) = 10.752

20.0424(156.7296) = 3140.8706624

3140.8706624 ÷ 2.3 = 1365.584192

1365.584192 × 18.6388 = 25472.261469696

Step 4: Calculate the final result:

28.5056 - 10.752 - 25472.261469696 = -25454.507869696

Therefore, the result of the expression 6.56×4.36-3.36(0.736+2.464)-20.0424(32.24×0.32+366.032×0.4):2.3×18.6388 is approximately -25454.507869696.
