Question

Помогите! Номер 57 под цифрами: 1,2,6,7

Answer 1

$2 {}^{2} \times {2}^{3} = {2}^{2 + 3} = 2 {}^{5} = 32 \\ {3}^{15} \div {3}^{11} = {3}^{15 - 11} = 3 {}^{4} = 81 \\ \frac{ {7}^{15} \div {7}^{12} }{ {7}^{2} } = \frac{ {7}^{15 - 12} }{ {7}^{2} } = \frac{ {7}^{3} }{ {7}^{2} } = 7$
$\frac{(0.2) {}^{14} \times {(0.2)}^{9} }{ {(0.2)}^{15} \times {(0.2)}^{6} } = \frac{ {(0.2)}^{14 + 9} }{ {(0.2)}^{15 + 6} } = \frac{ {(0.2)}^{23} }{ {(0.2)}^{21} } = {0.2}^{2} = 0.04$
