Explicație pas cu pas:
[tex]\sqrt{{3}^{5} } = \sqrt{ {3}^{4} \times 3 } = {3}^{2} \sqrt{3} = 9 \sqrt{3} \\[/tex]
[tex]\sqrt{( - 7)^{4}} = \sqrt{ {7}^{4} } = {7}^{2} = 49 \\[/tex]
[tex]( - \sqrt{2})^{2} = {( \sqrt{2} )}^{2} = 2 \\[/tex]
[tex]\sqrt{3} = \sqrt{3} \\[/tex]
[tex](5 \sqrt{7})^{2} = {5}^{2} \times 7 = 25 \times 7 = 175 \\ [/tex]
[tex]( \sqrt{3} )^{4 } = {3}^{2} = 9 \\ [/tex]
[tex]( - 5 \sqrt{3})^{2} = (5 \sqrt{3})^{2} = {5}^{2} \times 3 = 25 \times 3 = 75 \\ [/tex]
