Question

(18-16, 9) *3, 3-3: 7,5=​

Answer 1

( 18 - 16,9 ) * 3,3 - 3 : 7,5

(1) 18 - 16,9 = 1,1

(2) 1,1 * 3,3 = 3,63

(3) 3 : 7,5 = 0,4

(4) 3,63 - 0,4 = 3,23

Ответ: 3,23

Answer 2

To solve the 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 solve the expression step by step:

1. (18-16, 9) * 3 Here, we have a comma in the expression, which is not a standard mathematical notation. If we assume it's a mistake and remove the comma, then we have: (18-16, 9) * 3 = (18-16) * 3 = 2 * 3 = 6

2. 3 - 3 3 - 3 = 0

3. 7, 5 As there is a comma again, let's assume it's a mistake and remove the comma. 7, 5 = 75 (assuming it's a concatenation of two numbers)

Putting it all together: 6 * 3, 0 : 75

Now, we have an expression with a colon (":") in the middle, which is not standard notation either. If we consider the colon as division, then the expression becomes:

(6 * 3) / (0 : 75) = 18 / (0 / 75)

Now, we have a division by zero in the denominator, which is undefined in mathematics. Division by zero is not allowed.

Therefore, the expression " (18-16, 9) * 3, 3-3: 7,5" is not well-defined and cannot be solved. Please review the expression and ensure it is correctly formatted before attempting to solve it.
