Explicație pas cu pas:
a)
[tex](\sqrt{2}) ^{5} * (\sqrt{2}) ^{2} = 8\sqrt{2}[/tex]
[tex](\sqrt{2}) ^{5+2} = 8\sqrt{2}[/tex]
[tex](\sqrt{2}) ^{7} = 8\sqrt{2}[/tex]
[tex](\sqrt{2}) ^{2}*(\sqrt{2}) ^{2}*(\sqrt{2}) ^{2}*(\sqrt{2})= 8\sqrt{2}[/tex]
[tex]2*2*2*(\sqrt{2})= 8\sqrt{2}[/tex]
[tex]8*(\sqrt{2})= 8\sqrt{2}[/tex]
b)
[tex](\sqrt{3}) ^{4} * (\sqrt{3}) ^{3} = \sqrt{3^{7} }[/tex]
[tex](\sqrt{3}) ^{4+3} = \sqrt{3^{7} }[/tex]
[tex](\sqrt{3}) ^{7} = \sqrt{3^{7} }[/tex]
[tex]\sqrt{3^{7} } = \sqrt{3^{7} }[/tex]
