999*999 + 999+999+1
999( 999+1) + (999+1)
1000*1000
1000 වර්ගය හැදෙනව නම් වර්ග මූලෙට වර්ගෙ කැපෙනව.
මං බින්දු අඩුවෙන් හැදුවෙ කම්මැලි නිසා
එතකොට හරි බින්දු ගාණ දැම්මම
1000000.

999999^2 + 999999 + (999999+1)
Let, 999999=x
x^2 + 2x + 1=(x+1)^2
sq root of (x+1)^2 is (x+1)
The answer is 1 000 000

=999,999^2+1,999,999
=999,999^2+999,999+1,000,000
=999,999(999,999+1)+10^6
=999,999(10^6)+10^6
=10^6(999,999+1)
=10^6(10^6)
=10^6

999999, කියන්නෙ 1000000-1, 1999999 කියන්නෙ 2×1000000 -1, ලක්ශ දහයට x ආදෙශ කරල වර්ගය ප්‍රසාරනය කරානම් ගානට x වර්ගයක් ඇවිත් උත්තරෙ එනව

I just took X to 999999 as a substitution. However the answer I took is 10 to the power 6...😊

[@YohanLakshan-fk6uz]

[(10^6-1)^2 + 2×10^6 -1]
[10^12 + 1 - 2×10^6 +2×10^6 -1] = [10^12]
[10^12]^(1÷2) = 10^6

999,999^2 + 1,999,999
(1,000,000 - 1)^2 + (1,000,000 + 999,999)
10^{12} - 2,000,000 + 1 + 1,000,000 + 999,999
(10^6)^2 - 2,000,000 + 2,000,000
(10^6)^2 [වර්ගමූලය දැමූ විට වර්ගය ඉවත් වේ]
10^6 = 1,000,000

[@nethumsandaruwan]

=[(1000000-1)^2 + 1999999]^1%2
=1000000^2- 2000000+1 [phone]
=1000000
