mk cần gấp mong mn giúp đỡ. mk sẽ tk
tính giá trị biểu thức
a, 3^8 / 3^4 + 2^2 *2^3
b, 3* 4^2 -- 2 * 3^2
c, \(\frac{4^6\cdot3^4\cdot9^5}{6^{12}}\)
d, \(\frac{21^2\cdot14\cdot125}{35^36}\)
e,\(\frac{45^3\cdot20^4\cdot18^2}{180^5}\)
g, \(\frac{2^{13}+2^5}{2^{10}+2^2}\)
Tính giá trị biểu thức :
\(A=\frac{4^6\cdot3^4\cdot9^5}{6^{12}}\) ; \(B=\frac{21^2\cdot14\cdot125}{35^3\cdot6}\)
\(B=\frac{48^3\cdot50^5}{64^2\cdot125^2\cdot30^3}\)
Rút gọn
\(\frac{35\cdot9^{11}\cdot25^6-162\cdot5^{12}27^6}{17\cdot15^{12}\cdot9^{17}-54\cdot3^{20}\cdot125^4}\)
Tính :
\(A=1125:3^2+4^3\cdot125-125:5^2\)
Tính :
\(A=1125:3^2+4^3\cdot125-125:5^2\)
