Answer 1

Resposta:

$( \frac{1}{3} ) {}^{10} \times ( \frac{1}{3} ) {}^{20} \div ( \frac{1}{3} ) {}^{32} \\ ( \frac{1}{3} ) {}^{10} \times ( \frac{1}{3} ) {}^{20} \times ( \frac{1}{3} ) {}^{ - 32} \\ ( \frac{1}{3} ) {}^{10 +20 - 32} \\ ( \frac{1}{3} ) {}^{ - 2} \\ 3 {}^{2} \\ =9 \\ \\ \\ \frac{(2 \times 17) {}^{6} }{(17 {}^{2) {}^{3} } } \\ \frac{2 {}^{6} \times 17{}^{6} }{17 {}^{6} } \\ \frac{64 \times 17 {}^{6} }{17 {}^{6} } \: simplifca \: 17 {}^{6} \\ = 64$
