Cho 2 p/s
A= 10^19 +1/ 10^20+1
B= 10^20 +1/ 10^21+1
So sanh A va B
10^19+1/10^20+1 so sanh voi 10^20+1/10^21+1
so sanh 2 phan so
a=10^19+1/10^20+1;b=10^20+1+10^21+1
so sanh A,B .A=\(\frac{10^9+1}{10^8+1}\) ,,B\(\frac{10^{20}+1}{10^{21}+1}\)
So sánh phân số sau : A=\(\frac{^{10^{19}}+1}{10^{20}+1}\)và B = \(\frac{10^{20}+1}{10^{21}+1}\)
So sánh A và B biết
A=\(\frac{10^{19}+1}{10^{20}+1}\)
B=\(\frac{10^{20}+1}{10^{21}+1}\)
So sánh: \(\frac{10^{19}+1}{10^{20}+1}\) và \(\frac{10^{20}+1}{10^{21}+1}\)
So sanh :
A =\(\frac{20^{10}+1}{20^{10}-1}vaB=\frac{20^{10}-1}{20^{10}-3}\)
so sanh A=20^10+1/20^10-1 Va B=20^10-1/20^10-3
