#nxx2^2xx5=sqrt3600#

#=>nxx2^2xx5=sqrt(60^2)#

#=>nxx4xx5=60#

#=>n=60/(4xx5)=3#

# n = 3#

Explanation:

Do you mean to say #n \times 2^2 \times 5 = \sqrt{3600}#, then here is the process that you must do:

1) Find what #2^2 \times 5# equals to.
#2^2 \times 5 = 4 \times 5 = 20#

Now we have: #20n = \sqrt{3600}#

2) Find what #\sqrt{3600}# is.
#\sqrt{3600} = \sqrt{60 \times 60} = 60#

Now we have: #20n = 60#

3) Find what #n# is.
Divide both sides by 20.
#\frac{20n}{20} = \frac{60}{20}#
#n = 3#
