Question

alguém me ajudaaaa pfvr

Answer 1

B) 5$x^{6}$.x = 5$x^{7}$

C) -7y. (-2y) = 14$y^{2}$

D) (-2a).(6$a^{2}$).(5$a^{3}$ = -60$a^{6}$

E) ( -$\frac{mn}{2}$ ).($\frac{m}{7}$ ) = -$\frac{m^{2}n}{14}$

F) $\frac{9}{4} am^{2}.\frac{4}{9} a^{4} = \frac{36}{36}a^{5}m^{2}$ ou $a^{5} m^{2}$

G) $5a^{4}b . c^{3}.b^{2}c.4a^{2}c$ = $20a^{6} b^{3} c^{5}$

H) 4,5$y^{2} . 3y^{2} . y^{4}$ = 13,5$y^{7}$
