Odpowiedź:
2.
[tex] \frac{ {3}^{12} \div ( {3}^{6} \times {3}^{3} )}{{3}^{2} } = \frac{ {3}^{12} \div {3}^{9} }{ {3}^{2} } = \frac{ {3}^{3} }{ {3}^{2} } = 3[/tex]
3. a) 5^17
b) 9^19
c) (1 2/9)^7
4. a) (45:5)^2=(9)^2=81
b) (1 3/5*5/8)^10=(8/5*5/8)^10=1^10=1
c) (-0.9 : 9)^5=(-0,1)^5= -0,00001
d) (-3/16 : 1/16)^4=(-3/16*16/1)^4=(-3)^4=256
5. a) 2^5*2^3*2^4=2^12
b) 3^3*3^9:3^5=3^7
c) 2^6*2^4:2^9=2
6. (2^6)^8
(8^4)^4
7. nie mogę teraz
