Answer 1

Ответ:

68, 500, 520, 342

Пошаговое объяснение:

1) (30+4)•2=34*2=68

2) (200+50)•2=250*2=500

3) (100+30)•4=130*4=520

4) (50+7)•6=57*6=342

Answer 2

To compute the expressions, simply follow the order of operations, which is typically Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Let's calculate each expression step by step:

1. (30 + 4) • 2 First, solve the expression inside the parentheses: 30 + 4 = 34 Then, multiply the result by 2: 34 • 2 = 68

2. (200 + 50) • 2 First, solve the expression inside the parentheses: 200 + 50 = 250 Then, multiply the result by 2: 250 • 2 = 500

3. (100 + 30) • 4 First, solve the expression inside the parentheses: 100 + 30 = 130 Then, multiply the result by 4: 130 • 4 = 520

4. (50 + 7) • 6 First, solve the expression inside the parentheses: 50 + 7 = 57 Then, multiply the result by 6: 57 • 6 = 342

So, the values of the expressions are as follows:

1. (30 + 4) • 2 = 68
2. (200 + 50) • 2 = 500
3. (100 + 30) • 4 = 520
4. (50 + 7) • 6 = 342
