​

Answer 1

Explicație pas cu pas:

$( {5}^{ 7} \div {25}^{2} - {11}^{2} ) {}^{10} \div {8}^{6} = \\ ( {5}^{7} \div ( {5}^{2} ) {}^{2} - 121) {}^{10} \div {8}^{6} = \\ ({5}^{7} \div {5}^{4} - 121) {}^{10} \div {8}^{6} = \\ ( {5}^{3} -121) {}^{10} \div {8}^{6} = \\ (125 - 121) {}^{10} \div {8}^{6} = \\ {4}^{10} \div {8}^{6} = \\ ( {2}^{2} ) {}^{10} \div ( {2}^{3} ) {}^{6} = \\ {2}^{20} \div {2}^{18} = {2}^{2} = 4$
