[tex] {5}^{3} \div [ {2}^{5} - (7 \times {2}^{7} \div 14 - {7}^{0} ) \div {3}^{2} ][/tex]

[tex] = 125 \div [32 - (7 \times 128 \div 14 - 1) \div 9][/tex]

[tex] = 125 \div [32 - (896 \div 14 - 1) \div 9][/tex]

[tex] = 125 \div [32 - (64 - 1) \div 9][/tex]

[tex] = 125 \div (32 - 63 \div 9)[/tex]

[tex] = 125 \div (32 - 7)[/tex]

[tex] = 125 \div 25[/tex]

[tex] = 5[/tex]
