Question 683341
Is this it:
{{{ sqrt( -8*x^3 ) }}} ? If so:
You can break it up like this:
{{{ sqrt( -8*x^3 ) = sqrt( -1*8*x^3 ) }}}
{{{ sqrt(-1) * sqrt(8) * sqrt( x^3 ) }}}
{{{ i * 2*sqrt(2) * sqrt(x^3) }}}
{{{ 2*sqrt( 2x^3 )*i }}}
This is only slightly better, so you're
right- it isn't much of a simplification.
