Question

4) 5,4•3-9•5,4+6•6,4​

Answer 1

Ответ:

Будет 6

Пошаговое объяснение:

5,4 × 3 - 9 × 5,4 + 6 × 6,4​ =

= 16,2 - 48,6 + 38,4 =

= -32,4 + 38,4 = 6

Answer 2

To evaluate the expression, follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction):

1. First, perform the multiplications and divisions from left to right:

   5,4 * 3 = 16.2 (rounded to one decimal place) 9 * 5,4 = 48.6 6 * 6,4 = 38.4

2. Now, rewrite the expression with these results:

   5,4 * 3 - 9 * 5,4 + 6 * 6,4 16.2 - 48.6 + 38.4

3. Finally, perform the additions and subtractions from left to right:

   16.2 - 48.6 + 38.4 = 6.0

So, the value of the expression is 6.0.
