Question

efetue as seguintes multiplicações: a) a⁴ × a⁶
b) (1,5x²y) × (-0,3xy²
c) (-2,6abc) × (-1,2ab)
d) (-ac) × (-a⁴bc²)
e) (-0,1y³) × (+0,2y4)​

Answer 1

Resposta:

a)(-2,6abc).(-1,2ab)

3,12a²b²c

===================================================

b)(+1,5x³y).(-0,3xy²) = - 0,45x^4y³

===================================================

C)(-2,6abc).(-1,2ab) = 3,12a²b²c

===================================================

d) (-ac).(-a⁴bc²) = a^5bc³

===================================================

É)(-0,1y³).(+0,2y⁴) = - 0,02y^7
