Odpowiedź:
a) [tex]\sqrt{3*5*15} =\sqrt{15*15} =15[/tex]
b) [tex]\sqrt{ \frac{4}{5} *\frac{3}{5}*12 }= \sqrt{\frac{12}{25}*\frac{12}{1}}=\sqrt{\frac{12^2}{25} }= \frac{12}{5} = 2\frac{2}{5}[/tex]
c) [tex]\sqrt[3]{\frac{6}{5} * \frac{5}{2} *\frac{9}{8} } =\sqrt[3]{\frac{3}{1} * \frac{9}{8} } =\sqrt[3]{\frac{27}{8} } = \frac{3}{2}=1\frac{1}{2}[/tex]
Odpowiedź:
a) ... = √15 · √15 = 15
b) ... = √4/5 · 5/10 · 12 = √4/5 · 3/5 · 12 = √144/25 = 12/5 = 2,40
c) ... = ∛6/5 · ∛5/2 · ∛9/8 = ∛6/1 · 1/2 · 9/8 = ∛3/1 · 1/1 · 9/8 = ∛27/8 = 3/2 = 1,50
