Question

tính :

\(\frac{2^{10}.13.2^{10}.65}{2^8.104}\)

Answer 1

\(\frac{2^{10}.13.2^{10}.65}{2^8.104}=\frac{1024.13.1024.65}{256.104}\)

\(=\frac{1024.13.65}{256.104}=\frac{865280}{26642}\)

\(=32,5\)

Answer 2

\(\frac{2^{10}.13.2^{10}.65}{2^8.104}=\frac{2^{20}.13.65}{2^8.2^3.13}\)

\(=\frac{2^{20}.13.65}{2^{11}.13}\)

\(=2^9.65\)

\(=512.65\)

\(=33280\)

Answer 3

\(\frac{2^{10}.13.2^{10}.65}{2^8.104}=\frac{2^{20}.13^2.5}{2^{11}.13}=2^9.13.5=33280\)
