A=\(\frac{72^3.54^2}{108^4}=\frac{\left(2^3.9\right)^3.\left(6.9\right)^2}{\left(6.2.9\right)^4}=\frac{2^9.9^3.6^2.9^2}{6^4.2^4.9^4}=\frac{2^5.9}{6^2}=\frac{2^5.3^2}{\left(2.3\right)^2}=\frac{2^5.3^2}{2^2.3^2}=2^3=8\)
theo cách của mình là lấy máy tính bấm nó sẽ ra
hay thì mk nka
A=\(\frac{\left(9.8\right)^3.54^2}{\left(54.2\right)^4}=\frac{\left(9.8\right)^3.54^2}{54^4.2^4}=\)\(\frac{9^3.8^2}{54^2.2}=\frac{9.64}{36.2}=\frac{32}{4}=8\)
\(A=\frac{72^3.54^2}{108^4}\)
\(A=\frac{\left(2^3.9\right)^3.\left(6.9\right)^2}{\left(6.2.9\right)^4}\)
\(A=\frac{2^9.9^3.6^2.9^2}{6^4.2^4.9^4}\)
\(A=\frac{2^5.9}{6^2}\)
\(A=\frac{2^5.3^2}{\left(2.3\right)^2}\)
\(A=2^3=8\)
