Question 333642
{{{28/sqrt(8)}}} Start with the given expression



{{{(28*sqrt(8))/(sqrt(8)sqrt(8))}}}  Multiply both the numerator and the denominator by {{{sqrt(8)}}}



{{{(28*sqrt(8))/(8)}}} Multiply {{{sqrt(8)}}} and {{{sqrt(8)}}} to get {{{sqrt(8)*sqrt(8)=(sqrt(8))^2=8}}}



{{{(7*sqrt(8))/(2)}}} Reduce.



So {{{28/sqrt(8)=(7*sqrt(8))/(2)}}}
