Đáp án:
$B=2$
Giải thích các bước giải:
$B=\dfrac{(3.4.2^{16})^2}{11.2^{13}.4^{11}-16^9}$
$=\dfrac{3^2.4^2.(2^{16})^2}{11.2^{13}.4^{11}-16^9}$
$=\dfrac{3^2.(2^2)^2.2^{32}}{11.2^{13}.(2^2)^{11}-(2^4)^9}$
$=\dfrac{3^2.2^4.2^{32}}{11.2^{13}.2^{22}-2^{36}}$
$=\dfrac{3^2.2^{36}}{11.2^{35}-2^{36}}$
$=\dfrac{3^2.2^{36}}{2^{35}(11-2)}$
$=\dfrac{9.2^{36}}{2^{35}.9}$
$=2$
