Question

EXERCITIUL UNU DAU COROANA

Answer 1

Răspuns: $\bf A =\{0^{3},1^{3},2^{3},3^{3},4^{3},5^{3},6^{3}\}$

Explicație pas cu pas:

Salutare!

$\bf A =\{0,1,8,27,64,125,216\}\implies A =\{0^{3},1^{3},2^{3},3^{3},4^{3},5^{3},6^{3}\}$

$\bf 0^{3} = 0$

$\bf 1^{3} = 1$

$\bf 2^{3} = 8$

$\bf 4^{3} = 64$

$\bf 5^{3} = 125$

$\bf 6^{3} =216$

Answer 2

0^a=0=>0^3=0, unde a€N

1^a=1=>1^3=1, unde a€N

8=2^3

27=3^3

64=4^3

125=5^3

216=6^3

-putem scrie fiecare termen ca o putere cu exponentul 3

=>A={0^3;1^3;2^3;3^3;4^3;5^3;6^3}
