Explicație pas cu pas:
a) A={1, 2, 4, 8, 16, 32}; -> puteri ale lui 2
[tex]A = \{x \ | \ x = 2^k, \ 0 \leq k \leq 5 \}[/tex]
b) B= {1,2,2²,2³,2⁴,...,2¹⁰⁰}; -> puteri ale lui 2
[tex]B= \{x \ | \ x = 2^k, \ 0 \leq k \leq 100 \}[/tex]
c) C={16,25,36,49,64,81,100,121,144} -> patrate perfecte
[tex]C = \{x \ | \ x = k^2, \ 4 \leq k \leq 12 \}[/tex]
Succes!
