Accepted Answer

a) 7x × 12xy = 84x²y
б) 5,1a × (-0,03a²b) = -0,153a³b
в) -237p²q⁵ × (-0,001q⁹) = 0,237p²q¹⁴
г) \frac{2}{21}x³y × (-\frac{56}{3}xy^{4}) = -\frac{16}{9}x^{4}y^{5}
д) -\frac{27}{52}m × (-\frac{78}{81}mn^{6}) = \frac{13}{26}m^{2}n^{6} = \frac{1}{2}m^{2}n^{6}
е) -0,3c³ × 3\frac{1}{3}cd² = -0,3c³ × \frac{10}{3}cd² = -c^{4}d^{2}
