ta co( \(\frac{1}{243}\))9=(\(\frac{1}{3}\))45=(\(\frac{1}{81}\))11,25<(\(\frac{1}{83}\))13
So sánh :
a) \(\left(\frac{1}{243}\right)^9\) và \(\left(\frac{1}{83}\right)^{13}\)
b)1990^10+1990^9 và 1991^10
So sánh:
\(^{ }\left(\frac{1}{243}\right)^9\) và \(\left(\frac{1}{83}\right)^{13}\)
So sánh hai phân số :
\(\left(\frac{1}{243}\right)^9\)và \(\left(\frac{1}{83}\right)^{13}\)
so sánh 2 phân số:
\(\left[\frac{1}{243}\right]^9và\left[\frac{1}{83}\right]^{13}\)
So sánh hai phân số:
\(\left(\frac{1}{243}\right)^9và\left(\frac{1}{83}\right)^{13}\)
so sanh
\(\left(\frac{1}{243}\right)^9va\left(\frac{1}{83}\right)^{13}\)
SO SÁNH
