Question

Me ajudem a resolver pfvr, a professora irá olhar o caderno amanhã.

Resolva:
a) 8y²b / 5yb²

b) 9y² / 3x X y² / 4b

c) 2a⁴b³ / 3ab

d) 9y² / 3x X 4x⁶ / 2y

Answer 1

  a) 8y²b/5yb² = 8y/5b
 
  b) $\frac{9y^2}{3x} * \frac{y^2}{4b} = \frac{9y^4}{12bx}= \frac{3y^4}{4bx}$
   
  c) $\frac{2a^4b^3}{3ab} = \frac{2a^3b^2}{3}$
 
 d) $\frac{9y^2}{3x} * \frac{4x^6}{2y} = \frac{36y^2x^6}{6xy} = 6yx^5$
