#(pisqrt(2))/2#

Explanation:

Assumption: You mean #2pixxsqrt(4/32)#

#2pixxsqrt(2^2)/ sqrt(2xx4^2 )#

#2pixx2/(4sqrt2)#

#pi/sqrt2#

Not good practise to have a root in the denominator if you can do otherwise.

#pi/sqrt2xx1 color(white)("ddd")->color(white)("ddd")pi/sqrt2 xxsqrt2/sqrt2 color(white)("dddd")= color(white)("dddd")(pisqrt(2))/2#
