Easy method to recognize square root of any no. is to check the last 2 digits of a no. in the square-root.....(you should know square root values atleast from 1 to 9) As most competitive exams give multiple choice questions.
♡TIP: square of any no. ending with 5 can be concluded by multiplying it's preceding digit with next no.
for example 35²= 1225 [3*4=12 and 5 ka sq to pta hi hai always 25]
Similarly, 95²=9025
45²=2025
65²= 4225
Hope!It can help you.....
