Przedstaw liczbę w postaci potęi o wykładniku wymiernym
a)
b)
32⁸ * ∛64 = (2⁵)⁸ * 4³/³ = 2⁴⁰ * 4¹ = 2⁴⁰ * 2² = 2⁴² licznik
16⁹ * 2¹⁰ = (2⁴)⁹ * 2¹⁰ = 2³⁶ * 2¹⁰ = 2⁴⁶- mianownik
2⁴² : 2⁴⁶ = 2⁴²⁻⁴⁶ = 2⁻⁴ = (1/2)⁴ = 1/16
5 * ∛125 * (1/5)² = 5 * 5³/³ * 5⁻² = 5¹ * 5¹ * 5⁻² = 5⁰ licznik
25⁷ * ⁴√625 = (5²)⁷ * 5⁴/⁴ = 5¹⁴ * 5¹ = 5¹⁵ mianownik
5⁰ : 5¹⁵ = 5⁰⁻¹⁵ = 5⁻¹⁵
