Resposta:
a) √25[tex]a^{4}[/tex]
= √25 X √[tex]a^{4}[/tex]
= 5 X [tex]a^{\frac{4}{2} }[/tex]
= 5 X [tex]a^{2}[/tex]
= 5x[tex]a^{2}[/tex]
b) √4[tex]x^{2}[/tex]
= √4 X √[tex]x^{2}[/tex]
= √4 X [tex]x^{\frac{2}{2} }[/tex]
= 2 X x
= 2x
c) √16[tex]m^{2}[/tex]
√16 X √[tex]m^{2}[/tex]
= 4 X [tex]m^{\frac{2}{2} }[/tex]
= 4 X m
= 4m
d) √25[tex]x^{6}[/tex]
= √25 X √[tex]x^{6}[/tex]
= 5 X [tex]x^{\frac{6}{2} }[/tex]
= 5 X [tex]x^{3}[/tex]
= 5[tex]x^{3}[/tex]
e) √36[tex]x^{4}y^{2}[/tex]
= √36 X √[tex]x^{4}y^{2}[/tex]
= 6 X [tex]x^{\frac{4}{2} }x^{\frac{2}{2} }[/tex]
= 6 X [tex]x^{2}y[/tex]
= 6[tex]x^{2}y[/tex]
f) √36[tex]x^{4}y^{2}[/tex]
= √81 X √[tex]a^{2}b^{8}[/tex]
= 9 X [tex]x^{\frac{2}{2} }[/tex][tex]b^{\frac{8}{2} }[/tex]
= 9 X a[tex]b^{4}[/tex]
= 9a[tex]b^{4}[/tex]
