\(f\left(1\right)=\sqrt{5.1-1}=\sqrt{5-1}=\sqrt{4}=2\); \(f\left(\frac{1}{5}\right)=\sqrt{5.\frac{1}{5}-1}=\sqrt{1-1}=\sqrt{0}=0\)
Vì 2 > 0 nên \(f\left(1\right)>f\left(\frac{1}{5}\right)\)

We have : \(A=\)\(9x^2+8-12\)
=\(\left[\left(3x\right)^2-2.3x.2+4\right]+4\)
\(=\left(3x-2\right)^2+4\ge4\)(first)
But \(B=2\)(2)
From (1) and (2)

\(2A-A=\left(2+2^2+2^3+2^4+...+2^{60}\right)-\left(1+2+2^2+2^3+...+2^{59}\right)\)
=> A = 260 - 1
B = \(4^{25}.1024=\left(2^2\right)^{25}.2^{10}=2^{50}.2^{10}=2^{60}>2^{60}-1=A\)
Vậy A < B.
