i divide 18 by 2 and get 9 then ill get 9sqrt2
Mertsj
  • Mertsj
\[x \sqrt{2}=18\]
Mertsj
  • Mertsj
Divide both sides by sqrt 2

18sqrt2/sqrt 4
Mertsj
  • Mertsj
\[\frac{x \sqrt{2}}{\sqrt{2}}=\frac{18}{\sqrt{2}}\]
Mertsj
  • Mertsj
\[x=\frac{18}{\sqrt{2}}\]
Mertsj
  • Mertsj
Now simplify. Multiply numerator and denominator by sqrt2

i get 18sqrt2/sqrt4 and then i get sqrt18/4
Mertsj
  • Mertsj
\[\frac{18}{\sqrt{2}}\times \frac{\sqrt{2}}{\sqrt{2}}=\frac{18\sqrt{2}}{2}=9\sqrt{2}\]
