3 seconds ?…﻿

karthik kulkarni says:

how to find the square root of five digits or more?﻿

Wendy Botha says:

that is pretty cool﻿

AegeanGull says:

is there a way to know if the root that we have to calculate is a perfect square or not??﻿

XeroRon says:

Great math tip. thanks.﻿

Jay aNDe says:

I tried solving for square root of 5184 and 6084 but gave me the same answer as 78 for both using this method. Whereas it should have given me 72 for 5184.
Did I just find a glitch in the trick? Please lemme know.﻿

The Daily SciTech says:

Excellent method!﻿

milkYw4iMC says:

you are mixing stuff up, the squareroot of a number is always the positive one. so sqrt(576) = 24. Of course -sqrt(576) = -24 is also a solution to x² = 576, but the squareroot is always positive.﻿

Hardrive says:

Just one question: what about squares over 81,99?﻿

Nima Hanna says:

how do u do for example 99?﻿

Hacker Boy says:

To everyone who tells this or that number doesn't work..
This method is used for finding roots of already given perfect squares..not random numbers﻿
