Ta có \(2^n=...6;2^{n+1}=...2;2^{n+2}=...4;2^{n+3}=...8\) (với n là số tự nhiên chia hết cho 4)
Nên \(t=2^{2013}=...2\) Vậy chữ số tận cùng là 2
cho T = 2x2x2x2x.....x2x2( tich cua 2013 thua so 2) . T co chu so tan cung la may
Cho biet A la tich 2008* 2008*2008*.........*2008( Co 2009 thua so 2008)
Hoi tich tren co tan cung la chu so may
Tich 2 *12 * 22 *...*92 co tan cung la chu so...
hay cho biet tich A=2*12*22*32*.....*2002*2012
co chu so tan cung la chu so may
tich cua day 3 * 3 * 3 ..... * 3 ( co 2014 thua so 3 ) co chu so tan cung la bao nhieu
tich 2 * 12*22...*92 co tan cung la chu so
tich 2*12*22*......*92 co chu so tan cung la so nao
tich 2*12*22*.......*92 co tan cung la chu so
tich 1*5*6*11*17*28*...*118*191 co 2 chu so tan cung la nhung chu so nao
