\(A=\frac{7x\left(2x2\right)^5x3^{11}+2^{13}x\left(3x3\right)^5}{\left(2x3\right)^{10}+2^{12}x3^{10}}\)
\(A=\frac{7x2^{10}x3^{11}+2^{13}x3^{10}}{2^{10}x3^{10}+2^{12}x3^{10}}\)
tự làm tiếp
11x 3^22 x 3^7 - (3^2)^15 / 2^2 x 3^28
11x 3^29 - 3^30 / 4 x 3^28
11x 3^29 ( 1-3) / 4 x 3^28
11x 3^29 .2 / 4 x 3^28
11x3/ 2 = 33/2
\(E=\dfrac{11.3^{29}-3^{2^{15}}}{2.3^{14}.2.3^{14}}\)
\(=\dfrac{11.3-3^{30}}{2^2}=\dfrac{33-3^{30}}{4}\)
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

mk chỉ biết lm như thế này thôi !!!!!!!!!!!!!
A=\(\frac{5x\left(2^2x3^2\right)^9-2x\left(2^2x3\right)^{14}x3^4}{5x2^{28}x3^{18}-7x2^{29}x3^{18}}\)=\(\frac{5x2^{18}x3^{18}-2x2^{28}x3^{14}x3^4}{2^{28}x3^{18}x\left(5-7x2\right)}\)=\(\frac{5x2^{18}x3^{18}-2^{29}x3^{18}}{2^{28}x3^{18}x\left(-9\right)}\)=
= \(\frac{2^{18}x3^{18}\left(5-2^{11}\right)}{-9x2^{28}x3^{18}}=\frac{5-2^{11}}{-9x2^{10}}=\frac{2043}{9216}=\frac{227}{1024}\)
\(\dfrac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}=6^x\)
\(\Rightarrow\dfrac{11.3^{29}-3^{30}}{2^2.3^{28}}=6^x\)
\(\Leftrightarrow\dfrac{3^{29}\left(11-3\right)}{2^2.3^{28}}=6^x\)
\(\Leftrightarrow\dfrac{3.8}{4}=6^x\)
\(\Leftrightarrow6^1=6^x\)
\(\Leftrightarrow x=1\)
Vậy..
thank you very much ❤❤❤
