Question 210019
Rationalize the denominator.

{{{(10/(7sqrt(3)))}}}
<pre><font size = 4 color = "indigo"><b>
Multiply by {{{(sqrt(3)/sqrt(3))}}} which is really just {{{1}}},
and it doesn't change the value to multiply by {{{1}}}.

{{{(10/(7sqrt(3)))(sqrt(3)/sqrt(3))}}}

Multiply the tops and the bottoms:

{{{  (10sqrt(3)) /  (  7(sqrt(3))^2 )  )}}}

Replace the {{{(sqrt(3))^2}}} by {{{(3)}}}

{{{  (10sqrt(3)) /  (  7(3 )  )}}}

Replace {{{7(3)}}} by {{{21}}}

{{{  (10sqrt(3)) /21  }}}
