Question

Calcule as potências:

Answer 1

Resposta:

$a)( \frac{2}{3} ) {}^{ - 3} = \frac{3}{2} {}^{3} = \frac{27}{8}$

$b)( \frac{1}{4} ) {}^{ - 4} = \frac{3}{1} {}^{4} = \frac{81}{1}$

$c)( \frac{4}{3}) {}^{ - 2} = \frac{3}{4} {}^{2} = \frac{9}{16}$

$d) {2}^{ - 6} = \frac{1}{2} {}^{6} = \frac{1}{64}$

$e) {7}^{5} = 16807$

$f) {9}^{0} = 1$

$g)( {13}^{2}) {}^{6} = {13}^{12}$

$h)( \frac{7}{9}) {}^{20} \div ( \frac{7}{9}) {}^{15} = \frac{7}{9} {}^{5}$

$i) {7}^{5} . {7}^{4} = {7}^{9}$
