Ai nhanh mình tick cho nha
564+564+564+897+897+89-4=?
564 + 564 + 564 + 897 + 897 + 89 - 4 = 2674
dap an =3571 nha ban
tk vs nha
chuc ban hoc gioi
-564+[(-724)+564+224]
bằng -500 nhé
like cho mình nhé thank you

giải từng bước nhé :
-564+[(-724)+564+224]
= -564 - 724 + 564 + 224
= (-564+564)-(724-224)
= -500
-564+[(-724)+564+224]
=(-564)+(-724)+564+224
=[(-564)+564]+[(-724)+224
= 0 + (-500) = -500
564+[(-724)+564+224]
=(-564)+(-724)+564+224
=[(-564)+564]+[(-724)+224
= 0 + (-500) = -500
Tính nhanh;
(-564)+[(-724)+564+224]
(-564)+[(-724)+564+224]
=[(-564)+564]+[(-724)+224]

Thực hiện phép tính (tính nhanh nếu có thể):
- 564 - (324 - 564 - 224)
\(-564-\left(324-564-224\right)\\ =-564-324+564+224\\ =\left(-564+564\right)+\left(-324+224\right)\\ =0+\left(-100\right)\\ =-100\)
\(-564-\left(324-564-224\right)\)
\(=-564-324+564+224\)
\(=\left(-564+564\right)+\left(-324+224\right)\)
\(=-100\)
-564 - (324 - 564 - 224)
= -564 - 324 + 564 + 224
= (-564 + 564) + (224 - 324)
= 0 - 100
= -100
-879+[64+(-879)+36] ; -564+[(-724)+564+224] ; [461+(-78)+40]+(-461) ; [53+(-76)]-[-76-(-53)]
-879 + [64 + (-879) + 36]
= -879 + 64 - 879 + 36
= (-879 - 879) + (64 + 36)
= -1768 + 100 = -1668
-564 + [(-724) + 564 + 224
= -564 -724 + 564 + 224
= (-564 + 564) + (-724 + 224)
= 0 - 500 = - 500
