POZIOM A
[tex]2\cdot2^2\cdot2^5=2^{1+2+5}=2^8\\\\5^8:5^6=5^{8-6}=5^2\\\\(\frac{1}{3})^4\cdot(\frac{1}{3})^2\cdot(\frac{1}{3})^0=(\frac{1}{3})^{4+2+0}=(\frac{1}{3})^6[/tex]
POZIOM B

POZIOM C
[tex](5^2)^2=5^{2\cdot2}=5^4=5\cdot5\cdot5\cdot5=625\\\\((\frac{2}{3})^5)^0=(\frac{2}{3})^{5\cdot0}=(\frac{2}{3})^0=1\\\\((-1)^{10})^{30}=(-1)^{10\cdot30}=(-1)^{300}=1[/tex]
POZIOM D
