Bài 4. Hãy so sánh các số sau với \(1\):
a) \(\left ( 4,1 \right )^{2,7}\);
b) \(\left ( 0,2 \right )^{0,3}\);
c) \(\left ( 0,7 \right )^{3,2}\)4;
d) \(\left ( \sqrt{3} \right )^{0,4}\).

a) \(\left ( 4,1 \right )^{2,7}\)> \(\left ( 4,1 \right )^{0}= 1\) \(\Rightarrow\) \(\left ( 4,1 \right )^{2,7} > 1\).
b) \(\left ( 0,2 \right )^{0,3}\) < \(\left ( 0,2 \right )^{0}\) \(\Rightarrow\) \(\left ( 0,2 \right )^{0,3} < 1\).
c) \(\left ( 0,7 \right )^{3,2}\) < \(\left ( 0,7 \right )^{0}\) \(\Rightarrow\) \(\left ( 0,7 \right )^{3,2} < 1\).
d) \(\left ( \sqrt{3} \right )^{0,4}\)> \(\left ( \sqrt{3} \right )^{0}\)\(\Rightarrow\) \(\left ( \sqrt{3} \right )^{0,4} > 1\).
