Question

find the square root of the following number using in the identities.
I. 468
II. 1001
step by step​

Answer 1

Step-by-step explanation:

1. (468)2 = 219,024
2. 468 × 468 = 219,024
3. 1001
4. On decomposing,
5. ⇒ 1001=1000+1 ---- ( 1 )
6. Here, a=1000 and b=1
7. Squaring on both sides of equation ( 1 ),
8. ⇒ (10001)
9. 2
10. =(1000+1)
11. 2
13. =(1000)
14. 2
15. +2(1000)(1)+(1)
16. 2
17. [ (a+b)=a
18. 2
19. +2ab+b
20. 2
21. ]
22. =1000000+2000+1
23. =1002001
24. ∴ (1001)
25. 2
26. =1002001
