Question

efetue as multiplicações:

a) $(3ax)(\frac{3}{2}ax)$

b) $(-3ax)(2,4ax)$

Answer 1

Explicação passo-a-passo:

a) $(3ax).(\frac{3}{2}ax)=(3.\frac{3}{2}.a.a.x.x)=\frac{9}{2}a^{1+1}.x^{1+1}=\frac{9}{2}a^{2}x^{2}        =\frac{9a^{2}x^{2}}{2}$

b) $(-3ax).(2,4ax)=(-3.(2,4).a.a.x.x)=-7,2a^{1+1}x^{1+1}=-7,2a^{2}x^{2}$
