ai tích mình mình tích lại cho
Tính :
A = \(\dfrac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)
Tính:
\(A=\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)
\(B=\frac{\left(3.4.2^{16}\right)^2}{11.2^{13}.4^{11}-16^9}\)
\(C=\frac{4^5.9^{4-2.6^9}}{2^{10}.3^8+6^8.20}\)
Tính giá trị biểu thức sau:
