3.

a) = 2 · 3² · 11 = 2 · 99 = 198

b) = (-5)² · 2 = 25 · 2 = 50

c) = 4⁴ / 7² = 256 / 49

d) [tex]\sqrt{\sqrt[3]{27^{4} } } =\sqrt{\sqrt[3]{(3^{3} )^{4} } } =\sqrt{3^{4} } } =3^{2} =9[/tex]

e) = 6⁴ · (-2) = - 2 592

4.

a)  [tex]= \sqrt{4 *7}=2\sqrt{7}[/tex]

b) [tex]=\sqrt{3*7^{3}} =7\sqrt{21}[/tex]

c) [tex]= 7*11*\sqrt[3]{11} =77\sqrt[3]{11}[/tex]

d) [tex]=\sqrt[3]{2^{5}*3} =2\sqrt[3]{12}[/tex]

e) [tex]=\frac{2a\sqrt{3} }{b}[/tex]

f) [tex]=(-3)^{2} *2^{4} =9*16=144[/tex]

5.

a) [tex]= \sqrt{4*5} =\sqrt{20}[/tex]

b) [tex]= \sqrt{13^{2} *2} =\sqrt{338}[/tex]

c) [tex]= \sqrt[3]{8*5} =\sqrt[3]{40}[/tex]

d) [tex]\sqrt[3]{4^{3} *25} =\sqrt[3]{1600}[/tex]

e) [tex]=\sqrt{\frac{5x^{2} }{y^{2} } }[/tex]
