Zapisz w postaci potęgi liczby 2:
$\frac{ 2^{3}*( \frac{1}{8}: \frac{1}{4}) ^{2} }{2 ^{5}*(16: \frac{1}{16}) ^{3} }$

Zadanie 2
Oblicz:
$\frac{(3,6*10 ^{4})*(4,8*10 ^{5}) }{(1,8*10 ^{-10})*(2,4*10 ^{-6}) }$

marymax $\frac{2^3*(\frac{1}{8}:\frac{1}{4})^2}{2^5*(16:\frac{1}{16})^3}=\frac{2^3*(\frac{1}{8}*\frac{4}{1})^2}{2^5*(16*\frac{16}{1})^3}=\frac{2^3*(\frac{1}{2})^2}{2^5*256^3}=$

$\frac{2^3*2^{-2}}{2^5*(2^8)^3}=\frac{2^{3+(-2)}}{2^{5+24}}=\frac{2}{2^{29}}=2^{1-29}=2^{-28}$

2)
$\frac{(3,6*10 ^{4})*(4,8*10 ^{5}) }{(1,8*10 ^{-10})*(2,4*10 ^{-6}) }=\frac{3,6*4,8*10^9}{1,8*2,4*10^{-16}}=\frac{17,28*10^9}{4,32*10^{-16}}=4*10^{9-(-16)}=4*10^{25}$
