Question

What is the best way to find evalute (996)2

Answer 1

Answer:

992016

Step-by-step explanation:

you can do it by :-

(996)2= (1000-4)2

= (1000)2 + (4)2- 2x1000x4

1000000+16-8000= 992016

Answer 2

Answer:

992016

Step-by-step explanation:

996 is 4 less than 1000

so 4^2=16

we need to write 016 bcz in 1000, 3 zeros are there

then 996 is 4 less so we need to minus 4 from 996

then 996-4=992

so ans will be 992016...if a number would more than 10,100,1000 ...u can do with the same procedure. . ...ex-if a no is 1006

then it's square will be 1012036...bcz 6^2=036...

and 1006+6=1012...

hope it works out for giving an idea.....
