(5²×5³×5⁴)²:(5³)⁵-(11⁷)²:(11²)²:(11⁷×11⁰×11)= (5⁹)²:5¹⁵-11¹⁴:11⁴:11⁸=5¹⁸:5¹⁵-11²=5³-11²=125-121=4

[tex](5 {}^{9} ) {}^{2} \div (5 {}^{3} ) ^{5} - (11 {}^{7} ) {}^{2} \div (11 {}^{2} ) {}^{2} \div (11 {}^{7} \times 1 \times 11) = \\ 5 {}^{18} \div 5 ^{15} - 11 {}^{14} \div 11 {}^{4} \div 11 {}^{8} = \\ 5 {}^{3} - 11 {}^{14} \div 11 {}^{4} \div 11 {}^{8} = \\ 5 {}^{3} - 11 {}^{2} = \\ 125 - 11 {}^{2} = \\ 125 - 121 = \\ 4[/tex]
