b) √81 . (−2) + 10 ∶ (−4 + 2) − 37 =
c) −3 . 6 . (−1) + √4 . 7 − 1 8 − 60 ∶ (−3) =
d) 9(−20). (−4) + 1 + 35 ∶ (10 − 15) + (−2)/

Answer 1

Explicación paso a paso:

a) 4 . (−5) + 16 ∶ (−4) − 7 . (−6) =

-9-4+42= -13+42 = 29

b) √81 . (−2) + 10 ∶ (−4 + 2) − 37 =

9.(-2)+10:(-2)-37 = -18-5-37= -50

c) −3 . 6 . (−1) + √4 . 7 − 1 8 − 60 ∶ (−3) =

-3.-6+2.7-18+20= 18+14-18+20= 34

d) 9(−20). (−4) + 1 + 35 ∶ (10 − 15) + (−2)=

-180.-4+1+35:(-5)-2 = 720 +1-7-2 = 712
