Cześć!
Szczegółowe wyjaśnienie:
3. Oblicz wartość pierwiastków.
a)
[tex] \sqrt{7 {}^{4} \cdot7 {}^{2} } = 7 {}^{2} \cdot7 = \boxed{3}[/tex]
b)
[tex] \sqrt[3]{3 {}^{6} \cdot10 {}^{3} } = 3 {}^{2} \cdot10 = 9\cdot10 = \boxed{90}[/tex]
c)
[tex] \sqrt{5 {}^{4}\cdot2 {}^{6}\cdot7 {}^{2} } =5 {}^{2} \cdot2 {}^{3} \cdot7 = 25\cdot8\cdot7 = \boxed{1400}[/tex]
d)
[tex] \sqrt[3]{3 {}^{3} \cdot10 {}^{6} \cdot2 {}^{9} } = 3 \cdot10 {}^{2} \cdot2 {}^{3} = 3\cdot100\cdot8 = \boxed{2400}[/tex]
