Answer 1

Răspuns:

a)(2/3)^n=16/81=(2/3)⁴=> n=4

b)(1/7)^n=1/343=(1/7)³ =>n =3

c)(1 1/2)^n=3 375/1000

(3/2)^n=3375/1000=>(3/2)^n=27/8=(3/2)³

n=3

d)(2 1/2)^n=125/8=>(5/2)^n=(5/2)³=>n=3

e)1/3²)^n=1/729=>(1/9)^n=(1/9)³=>b=3

f)(1/8)^n=1/4³=>(1/2³)^n=(1/2⁶)

(1/2)^3n=(1/2)^6. =>3n=6 =>n=2

Answer 2
