Question

si A=-{-3-[2-(3-7)+5]} B=+2-{5-[3-(-4-2(-5]} calcular:A.B

Answer 1

Explicación paso a paso:

A=-{-3-[2-(3-7)+5]}

A=-{-3-[2-(-4)+5]}

A=-{-3-[2+4+5]}

A=-{-3-[11]}

A=-{-3-11}

A=- {-14}

A= 14

B=+2-{5-[3-(-4-2(-5))]}

B=+2-{5-[3-(-4+10)]}

B=+2-{5-[3-(6)]}

B=+2-{5-[-3]}

B=+2-{5+3}

B=+2-{8}

B=+2-8

B= -6

A×B= 14×(-6)

= -84
