Question 33042
(2sqrt5-2sqrt3)(sqrt10+sqrt6)
opening the brackets,
{{{ 2sqrt(5)sqrt(10) + 2sqrt(5)sqrt(6) - 2sqrt(3)sqrt(10) - 2sqrt(3)sqrt(6) }}}
{{{ 2sqrt(50) + 2sqrt(30) - 2sqrt(30) - 2sqrt(18) }}}
{{{ 2sqrt(25*2) - 2sqrt(9*2) }}}
{{{ 2(5)sqrt(2) - 2(3)sqrt(2) }}}
{{{ 10sqrt(2) - 6sqrt(2) }}}
{{{ 4sqrt(2) }}}
