Question

-8,27+7*(4,74:3/5-10)

Answer 1

- 8,27 + 7(4,74 : 3/5 - 10) = - 8,27 + 7(4,74 : 0,6 - 10) = - 8,27 + 7(7,9 - 10) =

= - 8,27 + 7 * (- 2,1) = - 8,27 - 14,7 = - 22,97

Answer 2

To solve this expression, let's follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The given expression is: -8,27 + 7 * (4,74 : 3 / 5 - 10)

1. Start with the parentheses: 4,74 : 3 / 5 - 10 First, perform the division: 4,74 / 3 ≈ 1.58 Then, perform the multiplication: 1.58 * 5 ≈ 7.9 Finally, subtract 10: 7.9 - 10 ≈ -2.1

2. Now, deal with the multiplication outside the parentheses: 7 * (-2.1) = -14.7

3. Lastly, add the result to the initial value: -8.27 + (-14.7) ≈ -22.97

So, the final result is approximately -22.97.
