Question

1) 8,4 -2.7(76 - 1,3(10 - 116)) - 15.7b:​

Answer 1

Ответ:

1/10*(28443/5-157b)

Answer 2

Let's break down and simplify the expression step by step:

1. Calculate the innermost parentheses first:

   • 10 - 116 = -106

2. Next, calculate the next set of parentheses:

   • 76 - 1.3 * (-106) = 76 + 137.8 = 213.8

3. Now, substitute this value back into the original expression: 8,4 - 2.7 * (213.8) - 15.7b

4. Calculate the multiplication: 8.4 - 577.86 - 15.7b

5. Now, subtract 577.86 from 8.4: 8.4 - 577.86 = -569.46

So, the simplified expression is: -569.46 - 15.7b
