95 - (129 - 74) : 5 + 2022⁰
= 95 - 55 : 5 + 1
= 95 - 11 + 1
= 95 - 10
= 85
-------
(-67) + 125 + (-33) + 75
= (125 + 75) - (67 + 33)
= 200 - 100
= 100
--------
86.(-108) + 86.9 - 86
= 86.(-108 + 9 - 1)
= 86.(-100)
= 8600
1: =(195-21):2+108=174:2+108=87+108=195
2: \(=16\left(444446-444444\right)=16\cdot2=32\)
3: \(=\dfrac{5^{3015}}{5^{3013}}-\dfrac{5^{3013}}{5^{3013}}=25-1=24\)
4: \(=125-\left[65-4^3\right]=125-1=124\)

a)\(27.65+27.35+300=27.\left(65+35\right)+300\)
\(=27.100+300=2700+300=3000\)
b)\(3838:\left[\left(190-6.5^2\right):4+3\right]\)
\(=3838:\left[\left(190-6.25\right):4+3\right]\)
\(=3838:\left[\left(190-150\right):4+3\right]\)
\(=3838:\left[40:4+3\right]=3838:\left[10+3\right]\)
\(=3838:13=\dfrac{3838}{13}\)
c)\(2022-x=2021\)

e)đề hỏi làm j thế bạn
1. -86 + ( -14)
= -86 - 14
= -100
2. 123 + ( -36)
= 123 - 36
= 87
3. ( -44) - ( -66)
= -44 + 66
= 22
4. -82 + (-28)
= -82 - 28
= -110
5. 83 + ( -17)
= 83 - 17
= 66

Có gì sai mong bạn sửa giúp mình nhé!
\(\text{36.( -14) (- 14).33 36.( 86) 67.( -14)}\)36.( -14) (- 14).33 36.( 86) 67.( -14)
\(=\left(-14\right).\left(33+67\right)+36.\left[\left(-14\right)+\left(-86\right)\right]\)\(=\left(-12\right)\)= ( -14 ) . ( 33 + 67 ) + 36.[ ( -14 ) + ( - 86 ) ]
