what is the square root of 1236248? Math homework!! No calculators allowed!!?

Answer 1

1111.8669 according to google.

Answer 2

There is a technique for finding the square root. It's a little complicated to explain here. Evidently, it's no longer taught!

You can approximate it.

mark off two digits at a time from the decimal point, then find the larges square that goes into the first block on the left or you can take two blocks: What you want to do is deal with the square roots of numbers up to 100:


1:23:62:48

what's the largest square you can get in 123 ? It's 11, put in one zero for each block represent the sqrt(100)

so you know that
1100< sqrt(1236248)<1200

Now 11^2 = 121, so subtract this out, leaving;
2:62:48

the largest square in 2 is 1
so, now you know that

1110 < sqrt(1236248) < 1120

...



That gives you an idea of how the method works. It is exact, just like long division is exact. You can carry out the process for as many decimal places as you like.
