Question

$( - 3 {x}^{2}).(5a {x}^{2}).(2 {a}^{3}$
me ajudem a fazer a resolução
​

Answer 1

Resposta:

$(-3{x}^{2}).(5a{x}^{2}).(2{a}^{3})=\\\\(-3*5*2)a^{(1+3)}x^{(2+2)}=\\\\-30a^{4}x^{4}$

Propriedades:

$(a^{m})^{n}=a^{m.n}\\\\\sqrt[n]{x^m} =x^{\frac{m}{n} }\\\\a^{m}a^{n}=a^{m+n}\\\\\frac{a^{m}}{a^{n}}=a^{m-n} \\\\a^{0}=1\\\\a^{1}=a$

Answer 2

(-3x^2) * (5ax^2) * 2a^3)

= -30 * x^4 * a^4
