Answer 1

Resposta:

a) √25$a^{4}$

  = √25 X √$a^{4}$

  = 5 X $a^{\frac{4}{2} }$

  = 5 X $a^{2}$

  = 5x$a^{2}$

b) √4$x^{2}$  

  = √4 X √$x^{2}$

 = √4 X $x^{\frac{2}{2} }$

 = 2 X x

  = 2x

c) √16$m^{2}$

  √16 X √$m^{2}$

  = 4 X $m^{\frac{2}{2} }$

  = 4 X m

  = 4m

d) √25$x^{6}$

 = √25 X √$x^{6}$

 = 5 X $x^{\frac{6}{2} }$

 = 5 X $x^{3}$

 = 5$x^{3}$    

e) √36$x^{4}y^{2}$

 = √36 X √$x^{4}y^{2}$

 = 6 X $x^{\frac{4}{2} }x^{\frac{2}{2} }$

 = 6 X $x^{2}y$

 = 6$x^{2}y$

f) √36$x^{4}y^{2}$

 = √81 X √$a^{2}b^{8}$

 = 9 X $x^{\frac{2}{2} }$$b^{\frac{8}{2} }$

 = 9 X a$b^{4}$

 = 9a$b^{4}$
