Question

-10,8:6/11-12,5*(2/9)³=?

Answer 1

Ответ равен -1141/45

Answer 2

To solve this expression, 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)

Let's go step by step:

1. Start with the expression inside the parentheses:

(2/9)³ = (2/9) * (2/9) * (2/9) = 8/729

2. Now we have:

-10,8:6/11 - 12,5 * (8/729)

3. Perform the division first:

-10,8 / 6/11 = -10.8 * 11/6 = -19.8

4. Now the expression becomes:

-19.8 - 12,5 * (8/729)

5. Perform the multiplication:

-12.5 * 8/729 = -12.5 * 8/729 = -100/729 = -1.23457... (approximately)

6. Now, the expression becomes:

-19.8 - 1.23457...

7. Finally, perform the subtraction:

-19.8 - 1.23457... ≈ -21.03457...

So, the approximate result of the expression is -21.03457...
