Answer 2

Відповідь:

Покрокове пояснення:

75679+(19003-3897)/26+3125*28

75679+15106/26+3125*28

75679+581+87500 = 163760

700000-(146*513+67223/13)

700000-(74898+5171)

700000-80069 = 619931

Answer 3

1. To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

First, let's simplify the expression inside the parentheses:

(19,003 – 3,897) = 15,106

Next, divide the result by 26:

15,106 ÷ 26 = 580.23 (rounded to two decimal places)

Now, let's multiply 3,125 by 28:

3,125 × 28 = 87,500

Finally, let's add all the values together:

75,679 + 580.23 + 87,500 = 163,759.23

Therefore, the result of the expression is approximately 163,759.23.

2. Let's simplify this expression step by step:

First, divide 67,223 by 13:

67,223 ÷ 13 = 5,170.23 (rounded to two decimal places)

Next, multiply 146 by 513:

146 × 513 = 74,898

Now, subtract the result from step 2 from 700,000:

700,000 - (74,898 + 5,170.23) = 619,931.77

Therefore, the result of the expression is approximately 619,931.77.
