Question 91072
  
  {{{sqrt(162x^6)/sqrt(64x^2)}}} = {{{sqrt(81*2*x^6)/sqrt(64x^2)}}} = {{{sqrt(81)*sqrt(2)*sqrt(x^6)/(sqrt(64)*sqrt(x^2))}}} = {{{(9x^3sqrt(2))/8x}}} = {{{(9*highlight(x^3)sqrt(2))/(8*highlight(x))}}} = {{{(9x^2*sqrt(2))/(4*sqrt(2)*sqrt(2))}}} = {{{(9x^2*cross(sqrt(2)))/(4*sqrt(2)*cross(sqrt(2)))}}} = {{{9x^2/4sqrt(2)}}}  Answer.

I have explained step by step how to solve such problems and I hope you have understood too.  All the best.
