2013 x X + X x 1/2013 - 2013 = 1/2013
2013x y + y x 1/2013 - 2013=1/2013
2013*X+X*\(\frac{1}{2013}\)-2013=\(\frac{1}{2013}\)
(1 – 2 + 3 – 4 + 5 – 6 + 7 – 8 +........– 98 + 99) x (2013 x 6 – 2013 – 2013 x 5)
What is the value of the digit in the ones place of the following?
A = 2013 x 2013 x 2013 x.......x 2013 x 2013
2011 thừa số 2013
Hãy chứng minh A = B , biết:
A = 1 + (1+ 2) + (1+ 2+ 3) + ...........+ ( 1+ 2+ 3+ 4+ ...+ 2013)
B = 2013 x 1 + 2012 x 2 + 2011 x 3 + ......+ 2 x 2012 + 1 x 2013
Cho A = 2012 x 2012 x 2012 x ... x 2012 x 2012 ( 2013 thừa số 2012 )
B = 2013 x 2013 x 2013 x ... x2013 x 2013 ( 2012 thừa số 2013 )
Hỏi ( A + B ) chia cho 5 sẽ dư mấy ?
A = 2012 x 2012 x 2012 x…….x 2012 x 2012 (2013 thừa số 2012) B = 2013 x 2013 x 2013 x ……..x 2013 x 2013 (2012 thừa số 2013) Hỏi A + B chia cho 5 có số dư là bao nhiêu? |
x * 2013 - x = 2013 * 2011 + 2013
