Bài trên là bài rút gon phân số
\(a)\frac{3^{10}.\left(-5\right)^{21}}{\left(-5\right)^{20}.3^{12}}=\frac{-5}{3^2}=\frac{-5}{9}\)
\(b)\frac{-11.13^7}{11^5.13^8}=\frac{-1}{11^4.13}\) (Bạn xem thử xem có sai đề không nhé)
\(c)\frac{2^{10}.3^{10}-2^{10}.3^9}{2^9.3^{10}}=\frac{2^{10}.3^9\left(3+1\right)}{2^9.3^{10}}=\frac{2.4}{3}=\frac{8}{3}\)
\(d)\frac{5^{11}.7^{12}+5^{11}.7^{11}}{5^{12}.7^{12}+9.5^{11}.7^{11}}=\frac{5^{11}.7^{11}\left(7+1\right)}{5^{11}.7^{11}\left(5.4+9\right)}=\frac{8}{20+9}=\frac{8}{29}\)

Tinh hop ly cac bieu thuc sau
a. \(A=\frac{3^{10}\times11+3^{10}\times5}{3^9\times2^4}\)
\(C=\frac{11\times3^{22}\times3^7-9^{15}}{\left(2\times3^{14}\right)^2}\)
a.. A = 310 × 11 + 310 × 5 / 39 × 24
A = 310 × (11 + 5) / 39 × 24
A = 310 × 16 / 39 × 24
A = 310 × 24 / 39 × 24
A = 3
C = 11 × 322 × 37 - 915 / (2 × 314)2
C = 11 × 329 - (32)15 / 22 × 328
C = 11 × 329 - 330 / 22 × 328
C = 329 × (11 - 3) / 22 × 328
C = 329 × 8 / 22 × 328
C = 329 × 23 / 22 × 328
C = 3 × 2
C = 6
