Question

a) 45 – { 4 . [( 9 . 12 – 14 . (-7) ) : ( 15 – 5 . (-2)³]}=
b) [ 25 – ( -18 : 3 )]. { 5 – [ 18 – ( 4 . (-2) – 4 )]}=

Answer 1

Resposta:

a) 45 – { 4 . [( 9 . 12 – 14 . (-7) ) : ( 15 – 5 . (-2)³]}=

=45-{4 [(108-98):(15-10)]}

=45-{4 [(10:5)]}

=45-{4.2}

=45-8

=37

b) [ 25 – ( -18 : 3 )]. { 5 – [ 18 – ( 4 . (-2) – 4 )]}=

[25–(−18:3)].{5–[18–(4.(−2)–4)]}

(25−(−183)).{5−(18−(4.(−2)−4))}

=(25−(−183)).{5−(18−(4.(−2)−4))}
