Question

А)23×8²-15×3³+1734:17б)5×11³-4×(76+13²×5)​

Answer 1

Ответ:

а)1169, б)2971

Пошаговое объяснение:

а)=23×64-15×27+1734:17=1472-405+102=1169

б)=5×1331-4×(76+169×5)=6655-4×(76+845)=6655-4×921=6655-3684=2971

Answer 2

Sure, let's solve the expressions step by step:

А) 23×8² - 15×3³ + 1734 ÷ 17

Step 1: Calculate the exponents 8² = 8 × 8 = 64 3³ = 3 × 3 × 3 = 27

Step 2: Perform the multiplications and divisions from left to right 23 × 64 - 15 × 27 + 1734 ÷ 17

Step 3: Perform the remaining multiplications and division 1472 - 405 + 102

Step 4: Perform the additions and subtractions from left to right 1472 - 405 + 102 = 1169 + 102 = 1271

So, the value of expression А) is 1271.

б) 5×11³ - 4×(76 + 13²×5)

Step 1: Calculate the exponent 11³ = 11 × 11 × 11 = 1331

Step 2: Perform the operations inside the parentheses first 13² = 13 × 13 = 169 76 + 169 × 5 = 76 + 845 = 921

Step 3: Perform the remaining multiplication and subtraction 5 × 1331 - 4 × 921

Step 4: Perform the multiplications 6655 - 3684

Step 5: Perform the subtraction 6655 - 3684 = 2971

So, the value of expression б) is 2971.
