\(\frac{\left(3.4.2^{16}\right)^2}{11.2^{13}.4^{11}-16^9}\)
\(=\frac{\left(3.2^{18}\right)^2}{11.2^{13}.\left(2^2\right)^{11}-\left(2^4\right)^9}\)
\(=\frac{3^2.2^{36}}{11.2^{35}-2^{36}}\)
\(=\frac{3^2.2^{36}}{2^{35}.\left(11-2\right)}\)
\(=\frac{3^2.2^{36}}{2^{35}.9}=\frac{3^2.2^{36}}{2^{35}.3^2}=2\)

= 3^2 . 2^4 . 2^32 / 11.2^13 .2^22 - 2^36
=3^2 . 2^36 / 11.2^35 - 2^36
=3^2 . 2^36 / 2^35 . ( 11+2)
= 9 . 2^36 / 2^35 . 13
= 9 . 2 / 13 = 18/13

\(\frac{\left(3.4.2^{16}\right)^2}{11.2^{13}.4^{11}-16^9}\)
\(=\frac{3^2.4^2.2^{32}}{11.2^{13}.\left(2^2\right)^{11}-\left(2^4\right)^9}\)
\(=\frac{9.\left(2^2\right)^2.2^{32}}{11.2^{13}.2^{22}-2^{36}}\)
\(=\frac{9.2^4.2^{32}}{11.2^{35}-2^{36}}\)
\(=\frac{9.2^{36}}{2^{35}.\left(11-2\right)}\)
\(=\frac{9.2^{35}.2}{2^{35}.9}\)
\(=2\)

*Bài làm:
\(\frac{3.4.2^{16}}{11.2^{13}.4^{11}-16^9}\)
= \(\frac{3.2^2.2^{16}}{11.2^{13}.\left(2^2\right)^{11}-\left(2^4\right)^9}\)
= \(\frac{3.2^{18}}{11.2^{13}.2^{22}-2^{36}}\)
= \(\frac{3.2^{18}}{11.2^{35}-2^{36}}\)
= \(\frac{3.2^{18}}{2^{18}.\left(11.2^{17}-2^{18}\right)}\)
= \(\frac{3}{\left(11.2^{17}-2^{18}\right)}\)
= \(\frac{3}{2^{17}.\left(11-2\right)}\)
= \(\frac{3}{2^{17}.9}\)
= \(\frac{1}{2^{17}.3}\)
*Vậy \(\frac{3.4.2^{16}}{11.2^{13}.4^{11}-16^9}\) = \(\frac{1}{2^{17}.3}\) .
