Question

Dau 18 puncteeeeee !!
1) calculati : a( [0,(3)] la puterea 3 b) [0,(6)] la puterea 3 c) [1,(3)] la puterea 3 d) [1,(6)] la puterea 3 e) [0,1(6)] la puterea 2 f) [0,8(3)] la puterea 2 g) [0,1(3)] la puterea 2 h) [0,2(6)] la puterea 2

2) determinati nr nat n , daca :
a ) $(1,25)^{n} = \frac{25}{16}$
b) $(0,75)^{n} } = \frac{27}{64}$

Answer 1

a) (1/3)^3=1/27; b) (2/3)^3=8/27; c) (4/3)^3=64/27; d) (5/3)^3=125/27; e) (1/6)^2=1/36; f) (5/6)^2=25/36; g) (2/15)^2=4/225; h) (4/15)^2=16/225
