Question

85,6•(20,2-18,51)+13,136;

Answer 1

$85.6 \times (20.2 - 18.51) + 13.136$

$85.6 + 1.69 + 13.136$

$144.664 + 13.136$

$157.8$

Answer 2

To solve this mathematical expression, you can follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction). Here's the step-by-step solution:

1. Calculate the expression inside the parentheses: 20.2 - 18.51 = 1.69

2. Multiply the result from step 1 by 85.6: 85.6 * 1.69 = 144.584

3. Add 13.136 to the result from step 2: 144.584 + 13.136 = 157.72

So, the final result is approximately 157.72.
