Answer:

#(8sqrt2)/7#

Explanation:

#sqrt2# has no perfect squares in it, so we can leave it the way it is for now. But we can rewrite this entire expression as

#sqrt(2)+(sqrt2/sqrt49)#

(because of the property #sqrt(a/b)=sqrta/sqrtb#)

Which simplifies to

#sqrt2+sqrt2/7#

We can factor out a #sqrt2# to get

#sqrt2(1+1/7)#

#=sqrt2(1 1/7)#

Changing to an improper fraction to get

#=sqrt2(8/7)#

which finally simplifies to

#(8sqrt2)/7#

Hope this helps!
