.85 is the correct answer

hrshpatidar: there is a short trick for this if we have to find the square of any no. which is multiple of 5 we can do this thing that for eg we have to find square of 25 for this we take 2 separately and for any no. we shuld multiply the no. ahead of 5 with the no. next to it like for 25 we multiply 2 by 3 i.e. 6 and behing 6 we write the square of 5 which is 25 hence we get 625 in reverse manner i did the same and got answer .85 as 72=8×9

hrshpatidar: did you get it

chanderkiranspartbz: yes

hrshpatidar: but i asked to smriti

hrshpatidar: okayy

hrshpatidar: need any more help
