Dear Akanksha, aapko kisne kaha ki 42 ka square root 1764 hota hai???...............42 ka square root 6.4807 hota hai approx 6.............42 ka square = 42*42 = 42^2 = 1764 hota hai.........isliye 1764 ka square root 42 diya gaya hai jo ki sahe hai.....

Know the difference between Square and square root, these two are two different things:

2 ka square 4 hota hai, 4 ka square root 2 hota hai

similarly, 42 ka square 1764 hota hai, 1764 ka square root 42 hota hai.

I think your mind absented here because its so fundamental.
