Oblicz a) [latex] sqrt{2} * sqrt{8} + sqrt[3]{54} : sqrt[3]{2} =[/latex] b) [latex] sqrt{3+ sqrt{42- sqrt{36} } } =[/latex] c) [latex] sqrt{12} + sqrt{27} - sqrt{3} =[/latex]

a)=√2*(2√2)+3³√2:³√2=4+3=7 b)  w załączniku c)=2√3+3√3-√3=5√3-√3=4√3

[latex]a) sqrt{2*8} + sqrt[3]{54:2} = sqrt{16} + sqrt[3]{27} = 4 + 3 = 7 b) sqrt{3 + sqrt{42- sqrt{36} } } = sqrt{3 + sqrt{42- 6 } } = sqrt{3 + sqrt{36 } } = sqrt{3+6} = sqrt{9} = 3 c) sqrt{4*3} + sqrt{9*3} - sqrt{3} = 2 sqrt{3} + 3 sqrt{3} - sqrt{3} = 5 sqrt{3} - sqrt{3} = 4 sqrt{3} [/latex]
