Question

which numeral will square 98

Answer 1

☺☺HEY MATE YOUR ANSWER IS HERE. ...☺☺

First take a guess and call it x1x1.

9898 is very close to 100100 (which is a perfect square), so my first guess is x1=10x1=10.

Now examine how far you are from the desired answer.

x21=(10)2=100x12=(10)2=100. So we are off by 22. Call this difference, dd, so d=2d=2.

Calculate d2x1=220=0.1d2x1=220=0.1

Our first guess overestimated the answer, so now we should subtract d2x1d2x1 from our initial guess (x1x1).

x2=10−0.1=9.9x2=10−0.1=9.9

As you can see x2x2 is already a quite good estimation of 98−−√=9.998=9.9 (98−−√≈9.899498≈9.8994)

If you want to find the answer with more accuracy, repeat the same procedure, only this time, take x2x2 as your first guess. And so on...
