\(\Rightarrow P=\frac{3^{11}\left(5+4.3\right)}{3^9\left(5^2-2^3\right)}\)

\(\Rightarrow P=\frac{3^2.17}{17}=3^2=9\)

P= 3¹¹(5+12) / 3⁹(25-8) 

P= 9.17 / 17

P= 9

.(5.3^11+4.3^12):(3^9.5^2-3^9.2^3)

=(5.3^11+4.3^12):(3^9.5^2-3^9.2^3)

=(5.3^11+4.3^11.3):[3^9.(5^2-2^3)]

tk nha

bai cua kacura dung nhung 4 dong cuoi la sai to

co khong co kieu phan phoi nhu vay ma phai thay la 3^11:3^9( nhan 17 chia 17 thi khi nao cung nhan duoc ket qua giong nhau)

                                                                           =3^2=9

1.(5.3^11+4.3^12):(3^9.5^2-3^9.2^3)

=(5.3^11+4.3^12):(3^9.5^2-3^9.2^3)

=(5.3^11+4.3^11.3):[3^9.(5^2-2^3)]

=(5.3^11+12.3^11):[3^9.17]

=3^11.(5+12):(3^9.17)

=(3^11.17):(3^9.17)

=17.(3^11:3^9)

=17.3^2

=17.9

=153

2.(1²+2²+3²+...+99²+100²).(36.333-108.111)

=2.(1²+2²+3²+...+99²+100²).(36.333-36.3.111)

=2.(1²+2²+3²+...+99²+100²).(36.333-36.333)

=2.(1²+2²+3²+...+99²+100²).0

=0

=\(\left[3^{11}.\left(5+4.3\right)\right]:\left[3^9.\left(5^2-2^3\right)\right]\)

=\(\left[3^{11}.17\right]:\left[3^9.17\right]=\left(3^{11}:3^9\right).17=9.17=153\)

\(\frac{5.3^{11}+4.3^{12}}{3^9.5^2-3^9.2^3}\)

\(=\frac{5.3^{11}+4.3.^{11}}{3^9.\left(5^2-2^3\right)}\)

\(=\frac{5.3^{11}+12.3^{11}}{3^9.\left(25-8\right)}\)

\(=\frac{3^{11}.\left(5+4\right)}{3^9.17}\)

\(=\frac{3^{11}.9}{3^9.17}\)

\(=\frac{3^9.3^2.9}{3^9.17}\)

\(=\frac{3^2.9}{17}\)

\(=\frac{9.9}{17}=\frac{81}{17}\)

Mình chuyển về phân số nhé. k mình nhé

P=(5.3¹¹+4.3¹²):(3⁹.5²-3⁹.2³)

=[3¹¹.(5+4.3)]:[3⁹.(5²-2³)]

=(3¹¹.17):(3⁹.17)

=3¹¹.17:3⁹:17

=3²=9

Vậy P=9
