The product of three consecutive even numbers, when divided by 8 is 720. What is the product of their square roots?

• 75.89 Let no be (x-2),x and (x+2) so when there product is divided by 8 we get 720, (x-2)(x)(x+2)/8=720 => x^3 - 4x =5760 => x=18 so nos are 16,18,20...and the product of there square roots are 75.89

• numbers are 16,18,20.
  as 16*18*20= 720*8
  product of their square roots = square root (16*18*20)= square root (16*360)= 4*6* root10= 24 root10.

• let no. be x,x+2,x+4 so x(x+2)(x+4)/8=720 so x(x+2)(x+4)=5760
  required is sqrt(x)*sqrt(x+2)*sqrt(x+4) is same as
  sqrt(x*(x+2)*(x+4))=sqrt(5760)=75.89
