Question 1059674
{{{ 5*( sqrt( 8 ) / sqrt( 5 ) ) }}}
{{{ 5*2*( sqrt(2) / sqrt(5) ) }}}
{{{ ( 5 / sqrt(5) )*2*sqrt(2) }}}
{{{ sqrt(5)*sqrt(2)*2 }}}
{{{ 2*sqrt(10) }}}
{{{ 2*3.1623 = 6.3246 }}}
----------------------------
check:
{{{ 6.3246 = 5*( sqrt( 8 ) / sqrt( 5 ) ) }}}
{{{ 6.3246 = 5*( 2.8284 / 2.2361 ) }}}
{{{ 6.3246 = 5*1.2649 }}}
{{{ 6.3246 = 6.3245 }}}
error due to rounding off
