Question

Calcule as expressões. A) (-x/2).(4y/3). 5. B) (-4a/3).(6ab/4) + Ab/2=

Answer 1

a) $( \frac{-x}{2} )*( \frac{4y}{3})*5= \frac{-10xy}{3}$

b) $( \frac{-4a}{3} )*( \frac{6ab}{4} )+ \frac{ab}{2}= \frac{-4a^2b+ab}{2}$

Answer 2

Resposta

a)

(-x/2)*(4y/3)*5. = -(10/3)xy

b)

(-4a/3)*(6ab/4) + ab/2

= ab * (-2a + 1/2)
