Question

Помогите пожалуйста:
Записать одночлен в стандартном вигляди - а)2x²y³0,5x⁴xy³•4
б)-1/2a⁴b²•6b⁶ab8/5a⁷b³

Answer 1

$a)2x {}^{2} y {}^{3} 0.5x {}^{4} xy {}^{3} \times 4 = x {}^{2 + 4} y {}^{3 + 3} x \times 4 = x {}^{6} y {}^{6} x {}^{1} \times 4 = x {}^{6 + 1} y {}^{6} \times 4 = x {}^{7} y {}^{6} \times 4 = x {}^{7} y {}^{6} \times 4$

$б) - \frac{1}{2} a {}^{4} b {}^{2} \times 6b {}^{6} ab \frac{8}{5} a {}^{7} b {}^{3} = - a {}^{4} b {}^{2} \times 3b {}^{6} ab \times \frac{8}{5} a {}^{7} b {}^{3} = - \frac{24}{5} a {}^{12} b {}^{12 } = - 4.8a {}^{12} b {}^{12}$
