Question

Fie numerele naturale a=2 la puterea 29 + 2 la puterea 40 ÷ 2 la puerea 11 si b= 12 la puterea 20 si 2 la puterea 40. a) aratati ca a=2 la puterea 30 si b) comparati numerele a si b

Answer 1

a=2^29+2^40:2¹¹

a=2^29+2^29

a=2^30

b=12^20+2^40

b=(12²)10+(2⁴)10

b=144^10+16^10

b=160^10

2^30 160^10

(2³)10 160^10
