Con procedimiento porfavor.

Answer 1

¡Hola¡

Resolver:

3 {2 (17-24+3 [5 (20-38) + 4 (5)] }

=3(2(−7+3(5(20−38)+(4)(5))))

=3(2(−7+3((5)(−18)+(4)(5))))

=3(2(−7+3(−90+(4)(5))))

=3(2(−7+3(−90+20)))

=3(2(−7+(3)(−70)))

=3(2(−7+−210))

=3(2)(−217)

=(3)(−434)

=−1302

- los paréntesis son multiplicación en varios casos.

[(5-4+15)- (-1-2+3)] + (5-14) - 15 + (4+7)

=1+15−(−1−2+3)+5−14−15+4+7

=16−(−1−2+3)+5−14−15+4+7

=16−(−3+3)+5−14−15+4+7

=16−0+5−14−15+4+7

=16+5−14−15+4+7

=16+−9−15+4+7

=7−15+4+7

=−8+4+7

=−8+11

=3

16 + 81÷9-9×8-9+12-10+25÷5

=16+9−(9)(8)−9+12−10+25÷5

=25−(9)(8)−9+12−10+25÷5

=25−72−9+12−10+25÷5

=−47−9+12−10+25÷5

=−56+12−10+25÷5

=−44−10+25÷5

=−54+25÷5

=−54+5

=−49
