You can estimate

100 x 100 = 10000

110 x 110 = 1100 + 11000 = 12100

Find the square root of 10890 by hand.

104^2 = 10816 which is 74 short

(104 + a)^2 = 10890

104^2 + 208a + a^2 = 104^2 + 74

a^2 + 208a = 74, but a < 1, so

a ~ 74/208 ~ 0.335 by long division

The square root of 10890 is about 104.335

Calculator gives 104.35516....

Where did you last see it ?

What do you MEAN by "find"? It is usual to use a calculator these days, why is that not your first resort ? If you mean "WITHOUT using a calculator", then say so. And say how you are supposed to go about "finding" it. No-one here is capable of reading your mind. Say exactly what it is that you want.
