zad 6
2¹⁰ ≈ 10³ ; 3¹⁰ ≈ 6 * 10⁴
1. 6¹⁰ = 2¹⁰ * 3¹⁰ ≈ 10³ * 6 * 10⁴ ≈ 6 * 10³⁺⁴ ≈ 6 * 10⁷ P
2. 1,5¹⁰ ≈ 57,7 ≈ 58 ≠ 60 F
zad 7
x = (1/3)³ = 3⁻³ ; y = 3⁶
1. x * y = 3⁻³ * 3⁶ = 3⁻³⁺⁶ = 3³ ≠ 3² F
2. x/y = 3⁻³/3⁶ = 3⁻³⁻⁶ = 3⁻⁹ = (1/3)⁹ P
zad 8
x = 2⁵
1. (2x)³ = 2³ * (2⁵)³ = 2³ * 2¹⁵ = 2³⁺¹⁵ = 2¹⁸ Odp: A
2. (x/2)³ = (2⁵)³/2³ = 2¹⁵/2³ = 2¹⁵⁻³ = 2¹² Odp: C
zad 9
x = 2²⁰ + 2¹⁰ , y = 2¹⁵ + 2¹⁵ = 2 * 2¹⁵ = 2¹⁺¹⁵ = 2¹⁶
TAK ponieważ C
