1. [tex](\frac{1}{4} )^5[/tex]
2. -81 + 8 * 3 = -81 + 24 = -57
3. (-0,4)^6 * (-0,4)^-4 = (-0,4)^2 = 0,16
4. (-1/5)^10 * 5^10 = (-1)^10 = 1
5. a) -1
b) 1
c) 0,064
d) -9
6. 1/3 * 27^5 = 3^-1 * (3^3)^5 = 3^-1 * 3^15 = 3^14
7. 3^-9 > 3^-12
3^3 = 27
Większa jest pierwsza 27 razy.
8.
a- (3/2)^4 * 2^5 = 81/4 * 32 = 648
b- 5,6 * [tex]\frac{1}{1000}[/tex] = [tex]\frac{5,6}{10000}[/tex]
c - (-1/5)^12 * 5^12 * (-1)^13 = (-1)^12 * (-1)^13 = 1 * (-1) = -1
c < b < a
Winno być.
