-472 + (235 - 28) - 35 - 350
= -472 + 207 - 35 - 350
= -265 - 35 - 350
= 300 - 350 = -50
-472 + (235 - 28) - (35 - 350)
= -472 + 235 - 28 - 35 + 350
= (-472 - 28) + (235 - 35) + 350
= -500 + 200 + 350
= -500 + 550
= 50
a: \(-472+\left(235-28\right)-\left(35-350\right)\)
\(=-472+235-28-35+350\)
\(=\left(-472-28\right)+\left(235-35\right)+350\)
=-500+350+200

b: \(91\cdot172+91\cdot13-91\cdot85\)
\(=91\cdot\left(172+13-85\right)\)
\(=91\cdot100=9100\)
c: \(798-298:\left[19-2\left(5^2-22\right)^2\right]\cdot1^{2023}\)
\(=798-298:\left[19-2\left(25-22\right)^2\right]\)
\(=798-298:\left[19-2\cdot3^2\right]\)
\(=798-298:\left(19-18\right)\)
=798-298
=500
\(=\dfrac{2^{12}\cdot3^4\left(3-1\right)}{2^{12}\cdot3^6}-\dfrac{5^{10}\cdot7^3\left(1-7\right)}{5^9\cdot7^3+5^9\cdot7^3\cdot2^3}\)
\(=\dfrac{-2}{9}-\dfrac{5\cdot\left(-6\right)}{9}=\dfrac{-2-5\cdot\left(-6\right)}{9}=\dfrac{-2+30}{9}=\dfrac{28}{9}\)
