Question

Oblicz ( przykład b i c)
​

Answer 1

Odpowiedź:

b)

[tex]0,25^{4} * \frac{28^{6}}{7^{6}} = (\frac{1}{4})^{4} * (\frac{28}{7})^{6} = 4^{-4} * 4^{6} = 4^{-4 + 6} = 4^{2} = 16[/tex]

c)

[tex]\frac{2^{6} * 5^{12} * 7^{6}}{3,5^{6}} / 10^{10} = \frac{2^{6} * 25^{6} * 7^{6}}{3,5^{6}} / 10^{10} = \frac{(2 * 25 * 7)^{6}}{3,5^{6}} / 10^{10} = \frac{350^{6}}{3,5^{6}} / 10^{10} = (\frac{350}{3,5})^{6} / 10^{10} =[/tex]

[tex]= 100^{6} / 10^{10} = 10^{12} / 10^{10} = 10^{12 - 10} = 10^{2} = 100[/tex]
