\(\dfrac{18}{5}+\dfrac{6}{35}=\dfrac{126}{35}+\dfrac{6}{35}=\dfrac{126+6}{35}=\dfrac{132}{35}\)\(\dfrac{18}{5}+\dfrac{6}{35}=\dfrac{126}{35}+\dfrac{6}{35}=\dfrac{126+6}{35}=\dfrac{132}{35}\)

\(\left(315.4+5-315\right):3^{16}\)
\(=\left(1260+5-315\right):3^{16}\)
\(=\left(1265-315\right):3^{16}\)
\(=950:3^{16}\)
\(=\dfrac{950}{3^{16}}\)

\(2^6và6^2\)
\(\Rightarrow2^6=\left(2^2\right)^6=2^{12}\)
\(\Rightarrow6^2=\left(6^6\right)^2=6^{12}\)
Vậy \(2^{12}< 6^{12}hay2^6< 6^2\)
