Question

5. La suma entre 5a2b y-8a2b.
26. Restar 4x3y2z + 8x3y2 de (5x3y22 + 2x3y2z).
17. De (12xyz + 3xyz) restar 8xyz.
e A -7a2b + 6a2 restarle la suma (9a2b + 7 a2)
y (13a2b - 4a2).​

Answer 1

Explicación paso a paso:

5a2b-8a2b= 2b(5a-8a)=2b-3a

(5x3y22+2x3y2z)-(4x3y2z+8x3y2)

-2x+-3x+20=-5x+20=5(4-x)

(12xyz+3xyz)-8xyz=15xyz-8xyz=7xyz

-7a2b+6a2-((9a2b+7a2)+(13a2b-4a2))

-7a2b+6a2-(22a2b+3a2)

-29a2b+a2

a2(1-29b)
