Odpowiedź:
a) 2√5 = [tex]\sqrt{4x5}[/tex] = [tex]\sqrt{20}[/tex]
b) 12√3 = [tex]\sqrt{144x3}[/tex] = [tex]\sqrt{432}[/tex]
c) 5/4√5 = [tex]\sqrt{\frac{25}{16}x5 }[/tex] = [tex]\sqrt{\frac{125}{16} }[/tex] = [tex]\sqrt{7,8125}[/tex]
d) 0,1√5 = [tex]\sqrt{0,01x5}[/tex] = [tex]\sqrt{0,05}[/tex]
e) 4∛15 = [tex]\sqrt[3]{64x15}[/tex] = [tex]\sqrt[3]{960}[/tex]
f) 1/3∛15 = [tex]\sqrt[3]{\frac{1}{27}x15 }[/tex] = [tex]\sqrt[3]{\frac{15}{27} }[/tex] = [tex]\sqrt[3]{0,(5)}[/tex]
