Question

Помогите пожалуйста !!!найдите значение: 4×8^3; 4×2^2; 4×5^3+2; (3+2)^2; 4×3^2-9×2; (7-3)^3.​

Answer 1

$4 \times 8 {}^{3} = 2 {}^{2} \times (2 {}^{3} ) {}^{3} = 2 {}^{2} \times 2 {}^{9} = 2 {}^{11} = 2048$

$4 \times 2 {}^{2} = 2 {}^{2} \times 2 {}^{2} = 2 {}^{4} = 16$

$4 \times 5 {}^{3} + 2 = 4 \times 125 + 2 = 500 + 2 = 502$

$(3 + 2) {}^{2} = 5 {}^{2} = 25$

$4 \times 3 {}^{2} - 9 \times 2 = 4 \times 9 - 9 \times 2 = 9 \times (4 - 2) = 9 \times 2 = 18$

$(7 - 3) {}^{3} = 4 {}^{3} = 64$

Answer 2

Давайте посчитаем значения выражений по очереди:

1. 4 × 8^3 8^3 = 8 × 8 × 8 = 512 4 × 512 = 2048

2. 4 × 2^2 2^2 = 2 × 2 = 4 4 × 4 = 16

3. 4 × 5^3 + 2 5^3 = 5 × 5 × 5 = 125 4 × 125 = 500 500 + 2 = 502

4. (3 + 2)^2 (3 + 2)^2 = 5^2 = 5 × 5 = 25

5. 4 × 3^2 - 9 × 2 3^2 = 3 × 3 = 9 4 × 9 = 36 9 × 2 = 18 36 - 18 = 18

6. (7 - 3)^3 (7 - 3)^3 = 4^3 = 4 × 4 × 4 = 64

Таким образом, значения выражений равны:

1. 4×8^3 = 2048
2. 4×2^2 = 16
3. 4×5^3+2 = 502
4. (3+2)^2 = 25
5. 4×3^2-9×2 = 18
6. (7-3)^3 = 64
