\(A=\frac{2013}{2014}+\frac{2014}{2015}+\frac{2013}{2013}+\frac{1}{2013}+\frac{1}{2013}=\left(\frac{2013}{2014}+\frac{1}{2013}\right)+\left(\frac{2014}{2015}+\frac{1}{2013}\right)+1\)
Ta có: \(\frac{2013}{2014}+\frac{1}{2013}>\frac{2013}{2014}+\frac{1}{2014}=\frac{2014}{2014}=1\)
\(\frac{2014}{2015}+\frac{1}{2013}>\frac{2014}{2015}+\frac{1}{2015}=\frac{2015}{2015}=1\)
=> A > 1+ 1 + 1 = 3
cho \(a=\frac{2013}{2014}+\frac{2014}{2015}+\frac{2015}{2013}\)
so sánh a với 3
\(\frac{2013}{2014}+\frac{2014}{2015}+\frac{2015}{2013}\). hãy so sánh với 3
cho A =\(\frac{2013}{2014}+\frac{2014}{2015}+\frac{2015}{2013}\).HAY SO SANH A VỚI 3
Cho biểu thức A= 2013/2014 + 2014/2015 + 2015/2013. Hãy so sánh A với 3.( Mọi người giải đầy đủ giúp mình nhá! Cảm ơn!)
cho biểu thức A= 2013/2024+2014/2025+2015/2013.HÃY so sánh A với 3
So sánh:
\(\frac{2013}{2014}+\frac{2014}{2015}+\frac{2015}{2016}\)và\(\frac{2013+2014+2015}{2014+2015+2016}\)
so sánh
\(\frac{2013}{2014}+\frac{2014}{2015}và\frac{2013+2014}{2014+2015}\)
So sánh A=\(\frac{2014^{2015}+1}{2014^{2015}+1}\) va B=\(\frac{2014^{2014}+1}{2014^{2013}+1}\)
SO SÁNH
ạ, A = \(A=\frac{2015^{2015}+1}{2015^{2014}+1}VÀB=\frac{2015^{2014}+1}{2015^{2013}+1}\)
