ayuda

Answer 1

Respuesta:

N= - 7xy⁴

M= 15xy⁴

P= xy⁴

Q=17xy⁴

Explicación paso a paso:

N= A+B

=(5xy⁴) +(-12xy⁴)

=5xy⁴-12xy⁴

= - 7xy⁴

M=A+D-C

=(5xy⁴) +(3xy⁴)-(-7xy⁴)

=5xy⁴+3xy⁴+7xy⁴

=15xy⁴

P=D+C+A

=(3xy⁴) +(-7xy⁴)+(5xy4)

=3xy⁴-7xy⁴+5xy⁴

=8xy⁴-7xy⁴

=xy⁴

Q=D-B-C-A

=(3xy⁴) - (-12xy⁴)-(-7xy⁴)-(5xy⁴)

=3xy⁴+12xy⁴+7xy⁴-5xy⁴

=22xy⁴-5xy⁴

=17xy⁴
