ko sai đâu bn

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

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

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)]

=(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

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)

mjk dịch đc nè''

1/ \(\frac{9.5^{20}.27^9-3.9^{15}.25^9}{7.3^{29}.125^6-3.3^9.15^{19}}\)

\(=\frac{5^{20}.3^{29}-3^{31}.5^{18}}{7.3^{29}.5^{18}-3^{29}.5^{19}}=\frac{3^{29}.5^{18}.\left(25-9\right)}{3^{29}.5^{18}.\left(7-5\right)}=\frac{16}{2}=8\)

CÁC BÀI CÒN LẠI TƯƠNG TỰ HẾT NHÉ E

A=-7/21 + (1+1/3)

=-1/3 + 1 + 1/3

=(1/3 + 1/3) +1

=2/3 +1

=2/3 + 3/3

=5/3

B=2/15 + (5/9 + -6/9)

=2/15 + -1/9

=6/45 + 5/45

=11/45

C=(-1/5 + 3/12) + -3/4

=-1/5 + (1/4 + -3/4)

=-1/5 + -1/2

=2/10 + -5/10

=3/10

k cho mik nha

A= -7/21 +(1+1/3) = 1

B= 2/15 +(5/9+-6/9) = 61/45C= (-1/5+3/12)+-3/4 = -7/10
