Sir ur tricks are really very helpful….
But in (998)2 i.e 998Γ998 the trick suggested by u is failed. Plz help…
You can do this way
998 x 998
998 x 9 = 8982 add two zero
998 x 9 = 8982 add one zero
998 x 8 = 7984
Add all three together
898200 + 89820 + 7984 = 996004
Short Process
998 * 998 = 99604
1000-998=2
2 x 2 = 4
998-2=996
99604 answer
Wao u r grt can u send some tips else.
answer should be 996004
wrong answer
if its 100 then prefix one zero to 4, since its 1000, prefix 2 zeros to 4 to make it a three digit number. then subtract 2 from 998,which is 996, so 996004
I know this is a abacus trickπ
Well done
Hi Priya,l The trick is working on 998 also. Plz check
for the numbers around 1000 we should add three digits in the last
for eg
1.998 (1000-2)
2*2=4 so 004 and 998-2=996
so answer is 996004
2.992 (1000-8)
8*8=064 and 992-8=984
answer is 984064
99*99/2*99*8/8*8
9801/1584/64
9960 0 4 this trick. never fails
but for this we should first calculate 99 square
use base 1000 method
998 -002
998 -002
____________________
(998-02)/(-002*-002)
996/004 is the answer
u solved it wrong
the trick works accurately till 999 correct yourself
114^2= base 100..,,114 is moew than 100 by 14.
step1: add 14 to 114….114+14=128
step 2: square of 14.,..,196..now put it in last…and carry 1…
final result is 12996.
same with numbers which are less than 100.
98^2= 100-98=2
now 98-2=”96″
2^2=”4″
put is at last..answer is 9604…remember to put a zero before 4… π π π
you can also do like this;
(998)2=(1000-2)2 i.e. (a-b)2
(a-b)2= a2-2ab+b2
=(1000)2 – 2(1000×2) + (2)2
=1000000 – 4000 + 4
=996004
Helpfull
β11256 plz tell how to solve.this is not perfect square
No its not a perfect square
very helpful..thanks..
for squre
for Example: squre of 30
Ans: 30 x 30=900
E.g. 33
Ans: 33 x 33= 1089
My shortcut:
(999)2 = (1000)2 – 1000 – 999
(998)2 = (1000)2 -1000 – 999 – 999 – 998
or
(998)2 = (999)2 – 999 – 998
Likewise
(1001)2 = (1000)2 + 1000 + 1001
(1002)2 = (1001)2 + 1001 + 1000
To know (84)2,
We know (85)2 = 7225 (hope you know this)
(84)2 = 7225 – 85 – 84 = 8056.
(31)2 = (30)2 + 30 + 31
To find square root, there is an easy method available.
Hi can u pls give a trick to solve square of 579 ?
plz 122 square give with solution .
122 square = (12)square + 2 x 12 x 2 + (2)square
= 144 + 48 + 4 = 14884
follow the given steps you can get the ans.
awesome trick sir mindblowing
it is v useful.thank you.also want some tricks for squre roots.its too hrd
pls give me square root of 1225. also give me the short trick for find square root of 5,6,7 digit
i want too
Plz give me square root of 326. Ur trick is not working
it’s a very helpful trick sir…thank u so much….
well its good. but i would like to share more about this…like if we want to find the value of sqare root. like 15625 = (?)^2.
so we simply take last digit which is “5”.
so now we got one value whose square having 5 in last,
and that is “5”.
put that 5 in last,
Now
take first 3 digits from 15625, which is 156
and the near by square value is 12^2=144
so the ans will be 125.
Hey Guys!!
Hope you are doing Great!!
