Question

Sendo  A = 3³.5.7 e B = 3.5.7 , calcule a raiz quadrada de A.B .
 
 
Preciso dessa resposta com o cálculo urgenteeeeeeee!

Answer 1

Sendo A= 3³.5.7 = 27.5.7
A = 945
Sendo B = 3.5.7
B = 105
Logo:

A.B = 945.105= 99225

√99225 = 315

Answer 2

A = 3³.5.7
B = 3.5.7 


$\sqrt{A.B}$

$= \sqrt{3^3.5.7.3.5.7} \\ \\ = \sqrt{3^4.5^2.7^2} \\ \\ = \sqrt{3^2.3^2.5^2.7^2} \\ \\ =3.3.5.7 \\ \\ = \boxed{\boxed{315}}$
