Answer 1

m e auydas no entiendo 4c+(-4c)=0

18a(2b)=2b(18a)

-9x(∜3y∙4z)=(-9x∙∜3y)∙4z

72x+0=72x

x(-7y+11z)=-7xy+11xz

9x√3y +9x√7y=9x(√3y +√7y)

(-91)+(91)=0

7a(8b)=8b(7a)

3x+(y-7z)=(3x+y)-7z

3/7 x (1)=3/7 x

4(3p-10q)=12p-40q

√(2&3) a-√(2&3) b=√(2&3)(a-b)

3x (1/3x)=1

3,1417abc +0= 3,1417abc

4xyz (7ab)=28abxyz

1/2 f-1/2 f=0

∛2 × 1/∛2=1

8n(3p-q+4r)=24np-8nq+32nr -

√5 × 3/7=3/7×√5

1/3 a × 5b= 5/2 ab
