zad 1
a) 5⁷ * 2⁷ = (5 * 2)⁷ = 10⁷
b) 6⁸ : 3⁸ = (6/3)⁸ = 2⁸
c) 0,4⁶ * 15⁶ = (0,4 * 15)⁶ = 6⁶
d) (3/5)⁵ : 3⁵ = (3/5 : 3)⁵ = (3/5 * 1/3)⁵ = (3/15)⁵ = (1/5)⁵ = 0,2⁵
e) (- 2,7)⁸ : (- 9/10)⁸ = (27/10 * 10/9)⁸ = 3⁸
zad 2
a) 2³ * 15³ = (2 * 15)³ = 30³ = 27000
b) 21⁴ : 7⁴ = (21/7)⁴ = 3⁴ = 81
c) 0,125¹⁹¹ * 8¹⁹¹ = (0,125 * 8)¹⁹¹ = 1¹⁹¹ = 1
d) 1,69² : 1,3² = (1,69 : 1,3)² = 1,3² = 1,69
