Question

Спростити вираз:
1) 4m×(-2,5) 3)-3m×2p×(-5c)

2)- 1/2 x×2y×6 4) -4x × 1 1/3 x2​

Answer 1

$1)4m \times ( - 2.5) = - 4m \times 2.5 = - 10m \\ 2) - \frac{1}{2} x \times 2y \times 6 = - xy \times 6 = - 6xy \\ 3) - 3m \times 2p \times ( - 5c) = 3m \times 2p \times 5c = 3cmp \\ 4) - 4x \times 1 \frac{1}{3} \times 2 = - 4x \times \frac{1}{3} \times 2 = - \frac{8}{3} x$
