Odpowiedź:
1.
a)
0,03¹ + 0,3³ = 0,03 + 0,027 = 0,057
b)
(1/2)³ - (1/3)² = 1/8 - 1/9 = 9/72 - 8/72 = 1/72
c)
2⁵ - ( 3² - 3³) = 32 - (9 - 27) = 32 - (- 18) = 32 + 18 = 40
2.
a)
2⁵ = 32
2⁷ = 128
2⁵ < 2⁷
b)
(1/2)⁵ = 1/32
(1/2)7 = 1/128
1/32 > 1/128
(1/2)⁵ > (1/2)⁷
c)
(- 1/2)⁵ = - 1/32
(- 1/2)⁷ = - 1/128
- 1/32 < - 1/128
(- 1/2)⁵ < (- 1/2)⁷
d)
4³ = 64
3⁴ = 81
4³ < 3⁴
e)
(- 5)³ = - 125
( - 4)³ = - 64
( - 5)³ < (- 4)³
f)
5³ = 125
4³ = 64
5³ > 4³
3.
5³ + 5³ + 5³ + 5³ + 5³ =5 * 5³ = 5¹⁺³ = 5⁴
