Question

2. Scrieţi ca putere cu baza 2: a) (2²); b) (2)²; c) (25); d) (2²); e) (24) 200; f) (29)². Dau coroana​

Answer 1

32 = 4 × 8 = 2² × 2³ = 2²⁺³ = 2⁵

b) 128 = 2⁷

128 = 4 × 32 = 2² × 2⁵ = 2²⁺⁵ = 2⁷

c) 512 = 2⁹

512 = 4 × 128 = 2² × 2⁷ = 2²⁺⁷ = 2⁹

d) 4³⁵ = 2⁷⁰

4³⁵ = (2²)³⁵ = 2²ˣ³⁵ = 2⁷⁰.

e) 16⁷ = 2²⁸

16⁷ = (4 · 4)⁷ = (2² · 2²)⁷ = (2²⁺²)⁷ = 2⁴ˣ⁷ = 2²⁸

f) 1024 = 2¹⁰

1024 = 2 × 512 = 2 × 2⁹ = 2¹⁺⁹ = 2¹. xa•xb= x a+b (xa) b =x a•b :)
