Question

Чему будет равно 3ac * 2 ca, 3ac+2ca,. 2ac*2ca, 3a²c²*2c²a² 2a³c⁴*2c⁵*a⁷ 2a²c²*2c²a²

Answer 1

Ответ:

$3ac \times 2ca = 6 {a}^{2} {c}^{2} \\ 3ac + 2ca = 5ac \\ 2ac \times 2ca = 4 {a}^{2} {c}^{2} \\ 3 {a}^{2} {c}^{2} \times 2 {c}^{2} {a}^{2} = 6 {a}^{4} {c}^{4} \\ 2 {a}^{3} {c}^{4} \times 2 {c}^{5} \times {a}^{7} = 4{a}^{10} {c}^{9} \\ 2 {a}^{2} {c}^{2} \times 2 {c}^{2} {a}^{2} = 4 {a}^{4} c ^{4}$

Answer 2

Давайте упростим каждое выражение:

1. 3ac * 2ca = 6a^2c^2

2. 3ac + 2ca = 5ac

3. 2ac * 2ca = 4a^2c^2

4. 3a²c² * 2c²a² = 6a^4c^4

5. 2a³c⁴ * 2c⁵ * a⁷ = 4a^11c^9

6. 2a²c² * 2c²a² = 8a^4c^4

Итак:

1. 6a^2c^2
2. 5ac
3. 4a^2c^2
4. 6a^4c^4
5. 4a^11c^9
6. 8a^4c^4
