Answer 1

Respuesta:

A. m4 z 4

   =16mz

B. n 3 z 4 + 3n − 5mn

   = 12nz+3n-5nm

C. n 3 z 4 + 3n − 4mnz − 3mn + 7m

 =12nz+3n-4nmz-3nm+7m

D. n 2 z 3 + n + 2mn + 8n

  =2 x 3nz+n+8n+2nm

  = 2 x 3nz+n+9n+2nm

  = 6nz+9n+nm

E.  n 3 + 3nz 4 − 3mzn4

 = 3n+12nz-12nmz

F.3nz 4 − 7mzn4

=12nz-28nmz

G. −7mzn4

= -28mnz

H. n + z 4 − 7m + z + n 4

= 4z+z+n+4n-7m

=4z+z+5n+7m

= 5z+5n-7n

i. ab+ab+ab+ab

=4ab

j.a+a+a+a+a

=5a
