Question

Помогите!!!!!!Пожалуйста!!!!!!!

Answer 1

а)
$frac{ {16}^{17} + {16}^{16} }{17} = frac{ {16}^{16} (16 + 1)}{17} = frac{ {16}^{16} times 17}{17} = {16}^{16}$
б)
$frac{ {5}^{12} + {5}^{10} }{13} = frac{ {5}^{10} ( {5}^{2} + 1)}{13} = frac{ {5}^{10} times 26 }{13} = 2 times {5}^{10}$
в)
$frac{ {49}^{5} + {7}^{8} }{350} = frac{ {7}^{10} + {7}^{8} }{350} = frac{ {7}^{8}( {7}^{2} + 1) }{350} = frac{ {7}^{8} times 50}{350} = frac{ {7}^{8} }{7} = {7}^{7}$
г)
$frac{ {321}^{3} - {123}^{3} }{198} = frac{(321 - 123)( {321}^{2} - 321 times 123 + {123}^{2} )}{198} = frac{198 times ( {321}^{2} - 321 times 123 + {123}^{2} )}{198} = 321^{2} - 321 times 123 + {123}^{2}$
