#3^(3sqrt2)=27^sqrt2#

We can take our original:

#81^sqrt2-:3^sqrt2#

and rewrite it this way:

#(3^4)^sqrt2/3^sqrt2#

which can then be written as:

#(3^(4sqrt2))/(3^sqrt2)#

and then we can write it as:

#(3^(3sqrt2+sqrt2))/(3^sqrt2)=(3^(3sqrt2)xx3^sqrt2)/(3^sqrt2)#

cancel the two like terms and get:

#(3^(3sqrt2)xxcancel(3^sqrt2))/cancel(3^sqrt2)=3^(3sqrt2)=27^sqrt2#
