Answer 1

а)а⁴в⁴с^6
б)-х^6*у^7*z^4
в)61,25*х^4*z^5
г)2с^4*d^7

Answer 2

а) $\frac{3}{5}a^{2} b^{2} c$✖$5ab^{2} c^{3}$✖$\frac{1}{3} ac^{2}$ = a²b²cab²c³ac² = a⁴b⁴c⁶

б) $\frac{1}{8}$ x⁵y⁴z³✖(-8xy³z) = -x⁵y⁴z³xy³z =➖x⁶y⁷z⁴

в) 3,5xz³ ✖($-3\frac{1}{2}$✖x²z$)$✖(-5xz) = 3,5 xz³✖$(-\frac{7}{2} x2z)$✖(-5xz) = $\frac{7}{2} xz^{3}$✖$\frac{7}{2} x^{2} z$✖5xz = $\frac{245}{4} x^{4} z^{5}$ = 61,25 x⁴z⁵

г) 2cd³✖$(-\frac{1}{2} cd^{2})$✖(-2c²d²) = cd³ cd² ✖ 2c² d² = 2c⁴d⁷
