Question

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

Answer 1

Ответ:

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