Question

1_ Simplifique as frações algébricas:
A) 9 ab/ 3 a*2 b*2

B) 3 a*3 c*5/24 a*4 c*2


C) 12 m*3 s*5/30 m*2 S*6


D) 8 (a+b)/ 2 (a*2 - b*2)

Answer 1

$\frac{9ab}{3a^2b^2} =\frac{3}{ab}$

$\frac{3a^3c^5}{24a^4c^2} =\frac{c^3}{8a}$

$\frac{12m^3s^5}{30m^2s^6} =\frac{2m}{5s}~$

$\frac{8(a + b)}{2(a^2 - b^2)}= \frac{8(a + b)}{2(a+b)(a-b)}=\frac{4}{a - b}$
