Question

Resolver las siguientes operaciones combinadas.
a)40:20-3.5+8:4+1=
b)(9-13).(-5+10)-[12:(-3)+(11)=
c)3√-125+4 3:(-8)-2.√81=

Answer 1

40/20-3(5)+8/4+1=
2-15+2+1=
10

(9-13)(-5+10)-[12/(-3)+(11)]=
(-4)(5)-(-4+11)=
-20-(7)=
-27

3√-125+4(3)/(-8)-2(√81)=
-5+12/(-8)-2(9)=
-5-3/2-18=
-23-3/2=
-49/2
