[tex](2 {}^{3} ) {}^{7} \div 4 {}^{9} + 3 {}^{0} \\ 2 {}^{21} \div (2 {}^{2} ) {}^{9} + 1 \\ 2 {}^{21} \div 2 {}^{18} + 1 \\ 2 {}^{3} + 1 \\ 8 + 1 \\ 9[/tex]
[tex]( {2}^{3}) {}^{7} \div (2 {}^{2} ) {}^{9} + 1 = \\ = 2 {}^{21} \div 2 {}^{18} + 1 \\ = 2 {}^{21 - 18} + 1 \\ = {2}^{3} + 1 = \\ = 8 + 1 = \\ = 9[/tex]
