Answer 1

Resposta:

(-3_2)2× (-3_2)2=6

(+5_4)2×(+5_4)2=20

(1_-2)5×(1-_2)5×(1-_2)5×(1-_2)5×(1-_2)5=2

Answer 2

Resposta:

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

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

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