giúp mk đi mơn các bạn nhìu
B=\(\frac{2^{19}.27^3+15.4^9.9^4}{6^9.2^{10}+12^{10}}\)
C=\(\frac{2^{13}.4^{11}-16^9}{\left(3.2^{17}\right)^2}\)
D=\(\frac{4^7.2^8}{3.2^{15}.16^2-5.2^2.\left(2^{10}\right)^2}\)
10.6^9-4^5.9^4/2^10.3^8+6^8.28
\(S=\frac{1}{2}:\frac{3}{2}:\frac{4}{3}:\frac{5}{4}:\frac{6}{5}:\frac{7}{6}:\frac{8}{7}:\frac{9}{8}:\frac{10}{9}\)
Tính: 4^5.9^4-10.6^9
2^10.3^8+6^8.28
B=\(\dfrac{2^{19}.27^3+15.4^9.9^4}{6^9+2^{10}.3^{10}}\)
