Tính A =\(\frac{15.3^{11}+4.27^4}{9^7}\)
\(A=\frac{15.3^{11}+4.27^4}{9^7}=\frac{3.5.3^{11}+4.3^{3.4}}{3^{2.7}}=\frac{3^{12}.5+3^{12}.4}{3^{14}}=\frac{3^{12}\left(5+4\right)}{3^{14}}=\frac{9}{3^2}=\frac{9}{9}=1\)

A=15.3^11+4.27^4:9^7
Rút Gọn
a, \(\frac{15.3^{11}+4.27^4}{9^7}\)
Tính giá trị biểu thức :
F = \(\frac{15.3^{11}+4.27^4}{9^7}\)
G = \(\frac{5.2^{13}.4^{11}-16^9}{\left(3.2^{17}\right)^2}\)
\(F=\frac{15.3^{11}+4.27^4}{9^7}=\frac{5.3.3^{11}+4.\left(3^3\right)^4}{\left(3^2\right)^7}=\frac{5.3^{12}+4.3^{12}}{3^{14}}=\frac{3^{12}.\left(5+4\right)}{3^{14}}=\frac{3^{12}.9}{3^{12}.9}=1\)
\(G=\frac{5.2^{13}.4^{11}-16^9}{\left(3.2^{17}\right)^2}\)
\(G=\frac{5.2^{13}.\left(2^2\right)^{11}-\left(2^4\right)^9}{3^2.2^{34}}\)
\(G=\frac{5.2^{13}.2^{22}-2^{36}}{3^2.2^{34}}\)
\(G=\frac{5.2^{35}-2^{36}}{3^2.2^{34}}\)
\(G=\frac{2^{35}.\left(5-2\right)}{3^2.2^{34}}\)
\(G=\frac{2^{35}.3}{3^2.2^{34}}=\frac{2}{3}\)

tính \(\frac{15.3^{11}+4.27^4}{9^7}\)
\(\frac{4^6.3^49^3}{6^{12}}\)
\(\frac{2^{11}-2^3}{2^9-2}\)
tính giúp mik nhé
15.3^11+4.27^4 Phần 9^7 em sẽ tick cho em trả lơif nhanh nhất nha
= 5.3.3^11+4.(3^3)^4/(3^2)^7
= 5.3^12+4.3^12/3^14
= 3^12.(5+4)/3.3^12.3^2
= 3^12.9/3^12.9 = 1
k mk nha
