Hey here i am going to share a trick on finding out square root of imperfect squares. First of all we should now what are imperfect squares.
Imperfect squares are the number whose square root are not integers like 2,3 etc whereas number like 4,9,16,25 are perfect square because there square roots are 2,3,4,5 respectively.
So lets look at the simplest method that can be applied for finding square root of imperfect squares. You only need to remember following formula.√x±y = √x ± y/2√x
Lets understand above formula of finding square root using some exampleExample: √17
First Split 17 such that you can find the nearest perfect square in our case we can split it us follows√16+1So here comparing with formula x=16 and y=1 putting it in formula we get √16 + 1/2√16
On simplifying we will get it as 4+1/(2*4)
that can be written as 4+1/8 ie., 4+0.125 = 4.125
Hence Sqrt of 17 comes out to be 4.125(approx)
These is more easier method as compared to traditional long division method of finding square root of imperfect squares. So give it a try and if you find out any problem the please comment below.
