Question

determine a raiz quadrada exata dos números
$\sqrt{1024}$
$\sqrt{6561}$
$\sqrt{ \frac{900}{196} }$
$\sqrt{23409}$

Answer 1

$\sqrt{1024} = 32$

32 X 32 = 1024

$\sqrt{6561}$ = 81

81 X 81 = 6561

$\sqrt{ \frac{900}{196} }$

$\sqrt{ \frac{225}{49} }$

$\frac{ \sqrt{225} }{ \sqrt{49} }$

$\frac{15}{ \sqrt{49} }$

$\frac{15}{7}$


$\sqrt{23409} = 153$

153 X 153= 23409
