bài 1: Tính:
a, A= \(\frac{7\times4^5\times3^{11}+2^{13}\times9^5}{6^{10}+2^{12}\times3^{10}}\)
b, G= \(\frac{11\times3^{22}\times3^7-9^{15}}{\left(2-3^{14}\right)^2}\)
Bài 10: Tính:
a, A = \(\frac{7\times4^5\times3^{11}+2^{13}\times9^5}{6^{10}+2^{12}\times3^{10}}\)
b, G = \(\frac{11\times3^{22}\times3^7-9^{15}}{\left(2-3^{14}\right)^2}\)
\(A=\frac{7x\left(2x2\right)^5x3^{11}+2^{13}x\left(3x3\right)^5}{\left(2x3\right)^{10}+2^{12}x3^{10}}\)
\(A=\frac{7x2^{10}x3^{11}+2^{13}x3^{10}}{2^{10}x3^{10}+2^{12}x3^{10}}\)

Tìm x :\(\dfrac{11\times3^{22}\times3^7-9^{15}}{\left(2\times3^{14}\right)^2}=6^x\)
\(\dfrac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}=6^x\)
\(\Rightarrow\dfrac{11.3^{29}-3^{30}}{2^2.3^{28}}=6^x\)
\(\Leftrightarrow\dfrac{3^{29}\left(11-3\right)}{2^2.3^{28}}=6^x\)
\(\Leftrightarrow\dfrac{3.8}{4}=6^x\)
\(\Leftrightarrow6^1=6^x\)
\(\Leftrightarrow x=1\)
Vậy..

Tinh hop ly cac bieu thuc sau
a. \(A=\frac{3^{10}\times11+3^{10}\times5}{3^9\times2^4}\)
\(C=\frac{11\times3^{22}\times3^7-9^{15}}{\left(2\times3^{14}\right)^2}\)
a.. A = 310 × 11 + 310 × 5 / 39 × 24
A = 310 × (11 + 5) / 39 × 24
A = 310 × 16 / 39 × 24
A = 310 × 24 / 39 × 24
A = 3
C = 11 × 322 × 37 - 915 / (2 × 314)2
C = 11 × 329 - (32)15 / 22 × 328
C = 11 × 329 - 330 / 22 × 328
C = 329 × (11 - 3) / 22 × 328
C = 329 × 8 / 22 × 328
C = 329 × 23 / 22 × 328
C = 3 × 2
C = 6
