Answer 1

ПОСМОТРИ, ТАК НАДО БЫЛО РЕШИТЬ. У ТРЕТЬЕГО ПРИМЕРА ЧЕТВЕРТОЕ ДЕЙСТВИЕ НЕ НАПИСАЛА, 77350+36036=113386.

Answer 2

a) 18 * 50 + 19770 - 9989

To find the value of this expression, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. Multiply 18 by 50: 18 * 50 = 900. 2. Add 19770 to the result: 900 + 19770 = 20670. 3. Subtract 9989 from the previous result: 20670 - 9989 = 10681.

Therefore, the value of the expression 18 * 50 + 19770 - 9989 is 10681.

b) 13908 * 2 - 5090 * 4

Again, let's follow the order of operations:

1. Multiply 13908 by 2: 13908 * 2 = 27816. 2. Multiply 5090 by 4: 5090 * 4 = 20360. 3. Subtract the second result from the first: 27816 - 20360 = 7456.

Therefore, the value of the expression 13908 * 2 - 5090 * 4 is 7456.

c) 11050 * 7 + 6006 * 60 : 10

Let's break down this expression step by step:

1. Multiply 11050 by 7: 11050 * 7 = 77350. 2. Multiply 6006 by 60: 6006 * 60 = 360360. 3. Divide the second result by 10: 360360 : 10 = 36036.

4. Add the first result to the third result: 77350 + 36036 = 113386.

Therefore, the value of the expression 11050 * 7 + 6006 * 60 : 10 is 113386.

I hope this helps! Let me know if you have any further questions.
