\(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)
\(=\frac{11.3^{22}.3^7-\left(3^2\right)^{15}}{2^2.3^{28}}\)
\(=\frac{11.3^{29}-3^{30}}{2^2.3^{28}}\)
\(=\frac{3^{29}.\left(11-3\right)}{2^2.3^{28}}\)
\(=\frac{3.8}{2^2}\)
\(=\frac{3.2^3}{2^2}\)
\(=3.2\)
\(=6\)
Chúc bạn học giỏi nha!!!
K cho mik vs nhé
