Question

6,4-2×(-16):(-0,1):400=... дайте ответ с решением

Answer 1

Пошаговое объяснение:

1) (-0,1): 400=-0,00025

2) 6,4-2= 4,4

3) 4,4*(-16) = -70, 4

4) -70,4:(-0,00025)=281600

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction:

1. First, resolve any operations inside parentheses/brackets.
2. Next, perform any exponentiation if present.
3. Then, perform multiplication and division from left to right.
4. Finally, perform addition and subtraction from left to right.

Let's solve step by step:

1. There are no parentheses or brackets to resolve.

2. There are no exponents in the expression.

3. Perform multiplication and division from left to right:

   6,4 - 2 × (-16) ÷ (-0,1) ÷ 400

   6,4 - (2 × (-16)) ÷ (-0,1) ÷ 400 (Using the negative sign as a unary operator)

   6,4 + 32 ÷ (-0,1) ÷ 400 (Simplify multiplication)

4. Now, perform division:

   6,4 + (32 ÷ (-0,1)) ÷ 400

   6,4 + (32 ÷ 0) ÷ 400 (Division by zero is undefined)

Since division by zero is undefined, the expression has no valid solution.

Therefore, the expression 6,4 - 2 × (-16) ÷ (-0,1) ÷ 400 has no valid numerical answer. It is undefined due to division by zero.
