Question

Como faz esse calculo por favor

Answer 1

$x\sqrt{2} = 8\\\\x = \frac{8}{\sqrt{2} } \\\\x = \frac{8.\sqrt{2} }{\sqrt{2} \sqrt{2} }\\\\x= \boxed{4\sqrt{2}}$

Answer 2

x✓2=8

x=8/✓2

racionalizando o denominador:

$x = \frac{8}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} }$

$x = \frac{8 \sqrt{2} }{2}$

x=4✓2
