Tính giá trị biểu thức:
\(A=\frac{11.3^{22}.3^7.9^{15}}{\left(2.3^{14}\right)^2}\)
\(A=\frac{11.3^{22}.3^7.9^{15}}{\left(2.3^{14}\right)^2}\)
\(A=\frac{11.3^{29}-3^{30}}{2^2.\left(3^{14}\right)^2}\)
\(A=\frac{3^{29}.\left(11-3\right)}{2^2.3^{28}}\)
\(A=\frac{3.2}{1.1}\)
\(A=\frac{6}{1}\)
\(A=6\)

\(a.\frac{\left(-5\right)^2.20^4}{8^2.\left(-125\right)}\)
\(b.\frac{15^{11}.5^7.9^2}{5^{18}.27^6}\)
Giúp mk với mai mk nộp r
a. \(\frac{\left(-5\right)^2.20^4}{8^2.\left(-125\right)}=\frac{\left(-5\right)^2.5^4.2^8}{2^6.\left(-5\right)^3}=\left(-5\right)^3.2^2=\left(-125\right).4=-500\)
b, \(\frac{15^{11}.5^7.9^2}{5^{18}.27^6}=\frac{3^{11}.5^{11}.5^7.3^4}{5^{18}.3^{18}}=\frac{3^{15}.5^{18}}{5^{18}.3^{18}}=\frac{1}{3^3}=\frac{1}{27}\)

ai làm nhanh t tick 10 cái
A=11.322.37-915/(2.314)2
A=11.329-915/22.328
A=11.329-(32)15/4.328
A=11.329-330/4.328
A=11.329-329.3/4.328
A=329.(11-3)/328.4
A=329.8/328.4
A=3.8/4
A=24/4
A=6

Tính
A=\(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)
tính giá trị biểu thức
\(\frac{11.3^{22}.3^8-9^{15}}{\left[2.3^{14}\right]^2}\)
Tính hợp lý biểu thức sau:
\(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)
ta có \(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}=\frac{11.3^{29}-\left(3^2\right)^{15}}{2^2.\left(3^{14}\right)^2}\)
= \(\frac{11.3^{29}-3^{30}}{2^2.3^{28}}=\frac{3^{29}\left(11-3\right)}{2^2.3^{28}}\)
= \(\frac{3^{29}.2^3}{2^2.3^{28}}=3.2=6\)
A = \(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)
\(\frac{11.3^{22}.3^7-9^{15}}{^{ }\left(2.3^{14}\right)^2}\)
\(\frac{11.3^{22}.3^7-19^{15}}{\left(2.3^{14}\right)^2}\)
