#(sqrt(6x^2)+4sqrt(8x^3))(sqrt(9x)-xsqrt(5x^5))#

FOIL:
#=sqrt(9*6*x^3)-xsqrt(6*5*x^7)+4sqrt(9*4*2*x^4)-4xsqrt(5*8*x^8)#

#=(3sqrt6) x^(3/2)-(sqrt30)*x*x^(7/2)+(24sqrt2)x^(4/2)-(8sqrt10)*x*x^(8/2)#

#=3sqrt6x^(3/2)-sqrt30x^(9/2)+24sqrt2x^2-8sqrt10x^5#

#=sqrt2(3sqrt3x^(3/2)-sqrt15x^(9/2)+24x^2-8sqrt5x^5)#
