Salut!
[tex]a)(0.3^{2} )^{3} = 0.3^{5} \\ 0.3 ^{2 \times 3} = 0.3^{5} \\ 0.3^{6} = 0.3 ^{2} este \: fals \\ [/tex]
[tex]b)(0.1 \times 3)^{2} = 0.3^{2} \\ 0.3 ^{2} = 0.3^{2} este \: adevarat \\ [/tex]
[tex]c)(0.2)^{3} + (0.2)^{2} = (0.2)^{5} \\ {2}^{3} + {2}^{2} = {2}^{5} \\ 2^{3} = 2 \times 2 \times 2 = 8 \\ 2^{2} = 2 \times 2 = 4 \\ {2}^{5} = 2 \times 2 \times 2 \times 2 \times 2 = 32 \\ 8 + 4 =32\\ 12 = 32 \: este \: fals[/tex]
[tex]d)(0.2)^{3} - (0.2)^{2} = 0.2 \\2^{3} - {2}^{2} = 2 \\ {2}^{3} = 2 \times 2 \times 2 = 8 \\ {2}^{2} = 2 \times 2 = 4 \\ 2 - 4 = 2 \: este \: fals[/tex]
O seara frumoasă!
