(-1)3+[(-5)(-8)]+ 3] 343 + 18 (3-4) 5+ (1/2)-(5)-

=(−3+(−5)(−8)+3)(343)+18(3−4)(5)+1/2−5

=(−3+40+3)(343)+18(3−4)(5)+1/2−5

=(37+3)(343)+18(3−4)(5)+1/2−5

=(40)(343)+18(3−4)(5)+1/2−5

=13720+18(3−4)(5)+1/2−5

=13720+(18)(−1)(5)+1/2−5

=13720+(−18)(5)+1/2−5

=13720+−90+1/2−5

=13630+1/2−5

=27261/2−5

=27251/2 → Respuesta.
