Answer:

align the decimal points and add as normal to get
#9.4005# (see note below)

Explanation:

#{: ("",3,".",4,,, ), ("+",6,".",0,0,0,5), ("=",9,".",4,0,0,5) :}#

Note : this assumes that #3.4# can be taken to be accurate to 5 decimal places. If it is only accurate to 2 places (i.e. it is in the range #[3.35,3.45)#) then the best answer would be #9.4#

Accuracy of a solution is limited to the accuracy of the least accurate value used to compute the solution.
