\(=\dfrac{98\cdot76\left(101-101\right)}{2021\cdot2022\cdot...\cdot2030}=0\)
\(\text{(98.7676-9898.76): (2021.2022.2023...2030)}\)
= \(\text{(752 248 - 752 248): (2021.2022.2023...2030)}\)
= \(\text{0 : (2021.2022.2023...2030)}\)
= \(0\)
\(B=\)\(\left(98.7676-9898.76\right):\left(2021.2022.2023....2030\right)\)
\(=(98.101.76-9898.76):\left(2021.2022.2023....2030\right)\)
\(=\left(9898.76-9898.76\right):\left(2021.2022.2023...2030\right)\)
\(=0:\left(2021.2022.2023....2030\right)\)
\(=0\)
