Question 135909
Actually, neither I nor anyone else can "solve the above equation."  That is because there is no equation.  There is no equal sign anywhere in the expression, nor are there any variables.  I can help you simplify the radical expression, however.


{{{ (0-(10/(sqrt(7))))+9(sqrt(7)) }}}
{{{ (-10/(sqrt(7)))+9(sqrt(7)) }}}


Lowest Common Denominator is {{{sqrt(7)}}}, so
{{{(-10+9(sqrt(7))^2)/sqrt(7) }}}
{{{(-10+63)/sqrt(7)}}}
{{{53/sqrt(7)}}}

Simplest form has no radicals in the denominator, so multiply by 1 in the form of {{{sqrt(7)/sqrt(7)}}}


{{{(53/sqrt(7))(sqrt(7)/sqrt(7))}}}
{{{(53sqrt(7))/7}}}  Done
