@muối

(-1/3) : (-5/6) = 2/5

\(\frac{-1}{3}:\frac{-5}{6}\)

\(=\frac{-1}{3}.\frac{6}{-5}\)

\(=\frac{-6}{-15}\)

\(=\frac{-2}{-5}\)

\(=\frac{2}{5}\)

6x^2-(x-3)(3x+2)-6

=6x^2-6x^2+x-9x-6-6

=-5x-12

[461 + (-78) + 40] + (-461)

= 461 + (-78) + 40 + (-461)

= [461 + (-461)] + (-78) + 40

= 0 + (-78) + 40

= -78 + 40

= -38

\(a,=\left(-4\right)\\ b,=\left(-70\right)\\ c,2002+\left[45-5^2\right]=2002+\left[45-25\right]\\ =2002+20=2022\)

1) 5 + (-9) = -(9 - 5) = -4

2) (-63) - 7 = -(63 + 7) = -70

3) 2002 + [45 - (9 - 4)²]

= 2002 + (45 - 25)

= 2002 + 20 = 2022

(128-97+34)-(34-97+228)+2021^1

=(31+34)-[(-63)+228]+1

=65-165+1

mik gửi bạn lời giải , chúc bạn học tốt nhóe ! 

=-11,254+7,35=-3,904

- 3 ,904

(-11,254) - (-7,35) 

=(-11,254) +7,35)=-3,904

Gọi tổng của phép tính trên là A

\(A=15+2^4+2^5+2^6+...+2^{2022}\)

\(\Rightarrow2A=2+2^2+...+2^{2023}\)

\(\Rightarrow A=2^{2023}-1\)
