Zad 7 b)log2 2^15 d)log2 32 h)log2 √2

Zad 9 a)log√2 2 b)log√2 4 c)log√2 64

Answer 1

Zad 7

b)log2 2^15= 15 * log2 2 = 15 * 1 = 15

d)log2 32= log2 2^5 = 5 * log2 2 = 5 * 1 = 5

h)log2 √2 = log2 2^(1/2) = 1/2 * log2 2 = 1/2 * 1 = 1/2

 

Zad 9

a)log√2 2= log√2 (√2)² = 2 * log√2 √2 = 2 * 1 = 2

b)log√2 4 = log√2 (√2)⁴ = 4 * log√2 √2 = 4 * 1 = 4

c)log√2 64 = log√2 [(√2)²]⁶ = log√2 (√2)¹² = 12 * log√2 √2 = 12 * 1 = 12
