\(\frac{11.3^{32}.3^7-9^{15}}{\left(2.3^{14}\right)^2}=\frac{11.3^{39}-3^{30}}{4.3^{28}}=\frac{3^{30}.\left(11.3^9-1\right)}{4.3^{28}}=\frac{9.\left(11.3^9-1\right)}{4}=487152\)

\(\frac{11.3^{22}.3^8-9^{15}}{\left(2.3^{14}\right)^2}=\frac{45}{2}\) Nhé

Tk mình nha

\(\frac{45}{2}\) nhé !

Học tốt !

A=11.3²².3⁷-9¹⁵/(2.3¹⁴)²

A=11.3²⁹-9¹⁵/2².3²⁸

A=11.3²⁹-(3²)¹⁵/4.3²⁸

A=11.3²⁹-3³⁰/4.3²⁸

A=11.3²⁹-3²⁹.3/4.3²⁸

A=3²⁹.(11-3)/3²⁸.4

A=3²⁹.8/3²⁸.4

A=3.8/4

A=24/4

A=6

ai tích mình mình tích lại cho

A=\(\dfrac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}=\dfrac{11.3^{29}-3^{29}.3}{2^2.3^{28}}=\dfrac{3^{29}.\left(11-3\right)}{2^2.3^{28}}=\dfrac{3^{29}.2^3}{2^2.3^{28}}=3.2=6\)

\(A=\dfrac{11\cdot3^{22}\cdot3^7-9^{15}}{\left(2\cdot3^{14}\right)^2}=\dfrac{11\cdot3^{29}-3^{30}}{2^2\cdot3^{28}}\)

\(=\dfrac{3^{29}\cdot2^3}{3^{28}\cdot2^2}=3\cdot2=6\)

ta có    \(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}=\frac{11.3^{29}-\left(3^2\right)^{15}}{2^2.\left(3^{14}\right)^2}\)

=  \(\frac{11.3^{29}-3^{30}}{2^2.3^{28}}=\frac{3^{29}\left(11-3\right)}{2^2.3^{28}}\)

=   \(\frac{3^{29}.2^3}{2^2.3^{28}}=3.2=6\)

a ) \(\frac{11\cdot3^{22}\cdot3^7-9^{15}}{\left(2\cdot3^{14}\right)^2}=\frac{11\cdot3^{29}-\left(3^2\right)^{15}}{2^2\cdot3^{28}}\)

\(=\frac{3^{28}\left(11\cdot3-3^2\right)}{2^2\cdot3^{28}}=\frac{33-9}{4}=\frac{24}{4}=6\)

b ) \(27^{16}\div9^{10}\)

\(=\left(3^3\right)^{16}\div\left(3^2\right)^{10}\)

\(=3^{48}\div3^{20}\)

\(=3^{48-20}\)

\(=3^{28}\)

Bg

a) \(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)

= \(\frac{11.3^{22}.3^7-3^{30}}{2^2.3^{28}}\)

= \(\frac{11.3^{29}-3.3^{29}}{4.3^{28}}\)

= \(\frac{8.3^{29}}{4.3^{28}}\)

= \(\frac{2.3}{1.1}\)

= 6

b) 27¹⁶ ÷ 9¹⁰ 

= 3^3.16 ÷ 3^2.10 

= 3⁴⁸ ÷ 3²⁰ 

= 3^{48 - 20} 

= 3²⁸
