Answer 1

Ответ:

1000-5*(130-80)=750

1) 130-80=50

2) 5*50= 250

3) 1000-250= 750

Answer 2

To correctly place the parentheses in the expression "1000-5*130-80=750" to obtain the result of 750, we need to prioritize the order of operations (PEMDAS/BODMAS) as follows:

1. Parentheses
2. Exponents (Powers and Roots)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's place the parentheses to get the correct result:

1000 - (5 * 130) - 80 = 750

Now, we can solve the expression step by step:

1. 1000 - (5 * 130) = 1000 - 650 = 350
2. 350 - 80 = 270

So, the expression with the correct placement of parentheses is "1000 - (5 * 130) - 80 = 750".
