So sánh
\(A=\frac{115^{17}+2}{115^{17}-1}\)
\(B=\frac{115^{17}}{115^{17}-3}\)
\(A=\frac{115^{17}+2}{115^{17}-1}=\frac{115^{17}}{115^{17}-\left(2+1\right)}=\frac{115^{17}}{115^{17}-3}\)
\(\Rightarrow A=B\)

Ta có :
A = \(\frac{115^{17}+2}{115^{17}-1}\)= \(\frac{115^{17}-1+3}{115^{17}-1}\)= 1 + \(\frac{3}{115^{17}-1}\)
B = \(\frac{115^{17}}{115^{17}-3}\)= \(\frac{115^{17}-3+3}{115^{17}-3}\)= 1 + \(\frac{3}{115^{17}-3}\)
Vì 11517 - 1 > 11517 - 3 nên \(\frac{3}{115^{17}-3}\) < \(\frac{3}{115^{17}-1}\)
Vậy :1 + \(\frac{3}{115^{17}-1}\) < 1 + \(\frac{3}{115^{17}-3}\) hay A < B

1150-(115+1150)+(115-39)
\(1150-\left(115+1150\right)+\left(115-39\right)\)
\(=1150-115-1150+115-39\)
\(=\left(1150-1150\right)+\left(-115+115\right)-39\)
\(=0+0-39=-39\)

1150 - (115 + 1150) + (115 - 39)
= 1150 - 1265 + 76
= -115 + 76
= -39
