Question

alguém me ajuda pfvr ​

Answer 1

a)

$( \frac{4}{5}) {}^{2} = \frac{ {4}^{2} }{ {5}^{2} } = \frac{16}{25}$

b)

$( - \frac{9}{8} ) {}^{2} = (\frac{9}{8} ) {}^{2} = \frac{ {9}^{2} }{ {8}^{2} } = \frac{81}{64}$

c)

$\frac{ {4}^{2} }{5} = \frac{16}{5}$

d)

$( - \frac{1}{2} ) {}^{5} = - ( \frac{1}{2} ) {}^{5} = - ( \frac{ {1}^{5} }{ {2}^{5} } ) = - \frac{1}{32}$

e)

$( - \frac{3}{10} ) {}^{2} = ( \frac{3}{10}) {}^{2} = \frac{ {3}^{2} }{ {10}^{2} } = \frac{ 9}{100}$

f)

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