\(A=\frac{72^3.54^2}{108}\)
A = ?
hướng dẫn em làm với nhé!
A=\(\frac{72^3.54^2}{108^4}\)
(Trình bày cách là ra giúp mình nhé)
Đúng mình tick cho
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=\(\frac{72^3.54^2}{108^4}\)
\(A=\frac{72^3.54^2}{108^4}=\frac{\left(2^3.3^2\right)^3.\left(2.3^3\right)^2}{\left(2^2.3^3\right)^4}=\frac{2^9.3^6.2^2.3^6}{2^8.3^{12}}=\frac{2^{11}.3^{12}}{2^8.3^{12}}=\frac{2^{11}}{2^8}=2^3=8\)
Tính \(A=\frac{72^3.54^2}{108^4}\)
\(A=\frac{72^3.54^2}{108^4}=\frac{\left(2^3.3^2\right)^3.\left(2.3^3\right)^2}{\left(2^2.3^3\right)^4}=\frac{2^9.3^6.2^2.3^6}{2^8.3^{12}}=\frac{2^{11}.3^{12}}{2^8.3^{12}}=\frac{2^3}{1}=8\)
Tính
\(\frac{72^3.54^2}{108^4}\)
\(=\frac{9^3.8^3.9^2.6^2}{9^4.3^4.4^4}=\frac{9^5.4^3.2^3.2^2.3^2}{9^4.4^4.3^4}\)\(=\frac{9.2^3.2^2}{4.3^2}=2^3=8\)
\(=\frac{9^3.8^3.9^2.6^2}{9^4.12^4}=\frac{9.4^3.2^3.3^2.2^2}{3^4.4^4}=\frac{9.2^3.2^2}{3^2.4}\) =23=8
\(\frac{72^3.54^2}{108^4}\)
=\(\frac{2^9.3^6.54^2}{54^4.2^4}\)=\(\frac{2^5.3^6}{54^2}\)=\(\frac{2^5.3^6}{2^2.3^6}\)=23
tích minh nha.
TÍNH:
a,\(\frac{72^3.54^2}{108^4}\)
b,\(\frac{2^{10}.13+2^{10}.65}{2^8.104}\)
c,\(\frac{2015+2014+2013+...+1}{2015-2014+2013-...+1}\)
b, \(\frac{2^{10}\left(13+65\right)}{2^8.104}\)
=\(\frac{2^2.78}{104}\)=\(\frac{312}{104}\)=3
\(A=\dfrac{72^3.54^2}{108^4}\)
\(A=\dfrac{\left(2^3\cdot3^2\right)^3\cdot\left(2\cdot3^3\right)^2}{\left(2^2\cdot3^3\right)^4}=\dfrac{2^9\cdot3^6\cdot2^2\cdot3^6}{2^8\cdot3^{12}}=2^3=8\)
Tính
\(\frac{72^3.54^2}{108^4}\)
\(=\frac{\left(2^3.3^2\right)^3.\left(2.3^3\right)^2}{\left(2^2.3^3\right)^4}=\frac{2^9.3^6.2^2.3^6}{2^8.3^{12}}=\frac{2^{9+2}.3^{6+6}}{2^8.3^{12}}=\frac{2^{11}.3^{12}}{2^8.3^{12}}=2^3=8\)
Thực hiện phép tính : \(\frac{72^3.54^2}{108^4}\)
\(\frac{373248.2916}{136048896}\)= \(\frac{1088391168}{136048896}\)
Vậy đáp án là: \(\frac{1088391168}{136048896}\)= \(8\)
