\(\frac{373248.2916}{136048896}\)= \(\frac{1088391168}{136048896}\)

Vậy đáp án là: \(\frac{1088391168}{136048896}\)= \(8\)

Kết quả là 8 hả bạn?

=\(\frac{1}{9}\)

=8

\(\dfrac{72^3.54^2}{108^4}\)

\(=\dfrac{18^3.4^3.18^2.3^2}{18^4.6^4}\)

\(=\dfrac{18^5.2^6.3^2}{18^4.2^4.3^4}\)

\(=\dfrac{18.2^2}{3^2}\)

\(=\dfrac{9.2.2^2}{9}\)

\(=2^3=8\)

\(D=\dfrac{72^3\cdot54^2}{108^4}=\dfrac{2^9\cdot3^6\cdot2^2\cdot3^6}{2^8\cdot3^{12}}=2^3=8\)

\(\frac{72^3.54^2}{108^4}=\frac{108^4.8}{108^4}=8\)

B = \(\frac{6272}{729}\)

=\(\frac{2^9.3^6.54^2}{54^4.2^4}\)=\(\frac{2^5.3^6}{54^2}\)=\(\frac{2^5.3^6}{2^2.3^6}\)=2³

^{tích minh nha.} 

a) \(\frac{72^3.54^2}{108^4}=\frac{\left(2^3.3^2\right)^3.\left(2.3^3\right)^2}{\left(2^2.3^3\right)^4}=\frac{2^9.3^6.2^2.3^6}{2^8.3^{12}}=\frac{2^{11}.3^{12}}{2^8.3^{12}}=2^3=8\)

b) \(\frac{3^{10}.11+3^{10}.5}{3^9.2^4}=\frac{3^{10}.\left(11+5\right)}{3^9.16}=\frac{3.16}{16}=3\)
