Question

Tính :
\(\frac{2^5.7+2^5}{2^5.5^2-2^5.3}\)

Answer 1

\(\frac{2^5.7+2^5}{2^5.5^2-2^5.3}=\frac{2^5.\left(7+1\right)}{2^5.\left(5^2-3\right)}=\frac{8}{22}\)

Answer 2

\(\frac{2^5.7+2^5}{2^5.5^2-2^5.3}\)

\(\frac{2^5.\left(7+1\right)}{2^5.\left(5^2-3\right)}\)=\(\frac{8}{22}=\frac{4}{11}\)

Answer 3

\(\frac{2^5.7+2^5}{2^5.5^2-2^5.3}\) =    \(\frac{2^5.7+2^5.1}{2^5.5^2-2^5.3}\)

                             =    \(\frac{2^5.\left(7+1\right)}{2^5.\left(5^2-3\right)}\)

                             =    \(\frac{8}{22}\)=    \(\frac{4}{11}\)

Answer 4

\(\frac{2^5.7+2^5}{2^5.5^2-2^5.3}=\frac{2^5.\left(7+1\right)}{2^5.\left(5^2-3\right)}\)

                        \(=\frac{2^5.8}{2^5.22}\)

                        \(=\frac{8}{22}\)

                         \(=\frac{4}{11}\)
