Odpowiedź:
a)
[tex]2*2^{3} * 8^{5}= \\2*2^{3} *(2^{2})^{5}=\\ 2*2^{3} * 2^{10}=\\ 2^{4}*2^{10}=\\2^{14}[/tex]
b)
[tex]10^{6}:5^{6} :2^{3}=\\(10:5)^{6} :2^{3}=\\2^6} :2^{3}= 2^{3}[/tex]
c)
[tex](4^{5})^{7} =( (2^{2} )^{5}) ^{7} = (2^{10} )^{7} =2^{70}[/tex]
d)
[tex]\frac{1}{8} *4^{5}= \frac{1}{8}*(2^{2} )^{5} = \frac{1}{8} * 2^{10}= 2\frac{1}{8}^{10}[/tex]
w ostatnim nie jestem pewna...
