Odpowiedź:
Zad 10
[tex] \frac{( { {3}^{2} })^{4} \times 3 }{ {3}^{8} } = \frac{ {3}^{8} \times 3}{ {3}^{8} } = 3[/tex]
odp.: D
Zad 11
[tex] \frac{ {2}^{7} }{ {5}^{2} } \times \frac{625}{32} = \frac{ {2}^{7} }{ {5}^{2} } \times \frac{ {5}^{4} }{ {2}^{5} } = {2}^{2} \times {5}^{2} = 4 \times 25 = 100[/tex]
Zad 12
[tex]0.013 \times {10}^{ - 10} = 1.3 \times {10}^{ - 2} \times {10}^{ - 10} = 1.3 \times {10}^{ - 12} [/tex]
czyli odp.: A
