Question

Rút gọn phân số: \(\frac{2^{16}-2^{14}}{2^{18}-2^{16}}\)

Answer 1

Ta có: \(\frac{2^{16}-2^{14}}{2^{18}-2^{16}}\)

\(=\frac{2^{14}\left(2^2-1\right)}{2^{16}\left(2^2-1\right)}=\frac{2^{14}}{2^{16}}=\frac{1}{4}\)

Answer 2

(2^16-2^14)/(2^18-2^16) =[2^14*(2^2 -1)]/[2^14*(2^4-2^2)] =(4-1)/(16-4)=3/12=1/4
