So Sánh\(\left(-\frac{1}{2}\right)^{513}va\left(-\frac{1}{3}\right)^{315}\)
So sánh \(\left(-\frac{1}{2}\right)^{513}\)và \(\left(-\frac{1}{3}\right)^{315}\)
So sánh : \(\left(\frac{1}{2^2}-1\right).\left(\frac{1}{3^2}-1\right).\left(\frac{1}{4^2}-1\right)...\left(\frac{1}{1000^2}-1\right)Và\frac{-1}{2}\)
So sánh các số :
\(\left(\frac{1}{2}\right)^1;\left(\frac{1}{3}\right)^{-1};\left(\frac{1}{2}\right)^2;\left(\frac{1}{4}\right)^{-1};\left(\frac{1}{3}\right)^{-2}\)
cho \(A=\left(\frac{1}{2^2}-1\right)\left(\frac{1}{3^2}-1\right)\left(\frac{1}{4^2}-1\right)...\left(\frac{1}{2016^2}-1\right)\left(\frac{1}{2017^2}-1\right)\)và b=-1/2
Hãy so sánh A với B
so sánh A và \(\frac{-1}{2}\)có A=\(\left(\frac{1}{2^2}-1\right).\left(\frac{1}{3^2}-1\right).\left(\frac{1}{4^2}-1\right).....\left(\frac{1}{100^2}-1\right)\)
Cho A= \(\left(\frac{1}{2^2}-1\right)\left(\frac{1}{3^2}-1\right)\left(\frac{1}{4^2}-1\right)...\left(\frac{1}{2013^2}-1\right)\left(\frac{1}{2014^2}-1\right)\) và B=\(\frac{-1}{2}\). Hãy so sánh A và B
