Question

pl. help me find out square root of 2304 using ones and tens method in detail...

Answer 1

23 04
Lets start with 04, check the last digit. Its 4 right. So, the square root must end with 2 or 8. As 2x2=4 and 8x8=64. Both ending in 4. The options are 2 or 4.

Now the digits 23. The nearest squares of 4 is 16 and 5 is 25. We choose the lesser (16 being lesser than 23) which is 4.

Now our answer is either 42 or 48.
Lets check 40x40=1600
And 50x50=2500

Clearly square of 50 is nearer to 2304. So, we choose a number closer to 50, which is 48. The square root of 2304 must be 48.

That's the only way I can explain..
