vo cau hoi tuong tu nha

Ai tick mình lên 160 với

a . 297+150:(493-47.10+7                                         b, 728:(73.3,54+0,17.25+3,54.27+0,23.25

=297+150:(493-470+7)                                               =728:[(73.3,54+3,54.27)+(0,23.25+0,17.25)]

=297+150:30                                                             =728:[3,54.(73+27)+25.(0,17+0,23)]

=297+5                                                                     =728:(3,54.100+25.0,4)

=302                                                                         =728:(354+10)

                                                                                =728:364

                                                                                =2

'.' là dấu phẩy

25947,58 nhé bạn

3.54 X 73 + 0.23 X 25 + 3.54 X 27 +0.77 X 25

= 3.54X(73+27)+25X(0.23+0.77)

=354+25

=400

3,54.73+0,23.25+3,54.27+0,77.25

=(3,54.73+3,54.27)+(0,23.25+0,77.25)

=3,54.(73+27)+25.(0,23+0,77)

=3,54.100+25.1

=379

\(A=\dfrac{27^3.54^2}{108^4}\)

\(=\dfrac{\left(3^3\right)^3.\left(3^3.2\right)^2}{\left(2^2.3^3\right)^4}\)

\(=\dfrac{3^9.3^6.2^2}{2^8.3^{12}}\)

\(=\dfrac{3^{15}.2^2}{2^8.3^{12}}\)

\(=\dfrac{3^3}{2^5}=\dfrac{27}{32}\)

Vậy A =\(\dfrac{27}{32}\)

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  

Trình bày cách là ra giúp mình mà

\(A=\frac{72^3.54^2}{108}=\frac{\left(2^3.3^2\right)^2.\left(2.3^3\right)^2}{2^2.3^3}=\frac{2^6.3^4.2^2.3^6}{2^2.3^3}=\frac{2^8.3^{10}}{2^2.3^3}\)

\(A=2^6.3^7\)

\(\frac{72^3.54^2}{108}\)

\(=\frac{2^9.3^6.2^2.3^6}{2^2.3^3}\)

\(=\frac{2^{11}.3^{12}}{2^2.3^3}\)

\(=2^9.3^9\)

\(=6^9\)

A = 72³ . 54² / 108 = 6⁹

=8

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

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

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

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

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

\(=2^3=8\)

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