a) Ta có: \(\left(2^2\right)^3\cdot4^5\)
\(=2^6\cdot2^{10}\)
\(=2^{16}=65536\)
b) Ta có: \(\left[\left(-4\right)^2\right]^2\cdot6\)
\(=16^2\cdot6\)
\(=256\cdot6=1536\)
c) Ta có: \(\frac{16}{25}\cdot\left(\frac{4}{5}\right)^3\)
\(=\left(\frac{4}{5}\right)^2\cdot\left(\frac{4}{5}\right)^3\)
\(=\left(\frac{4}{5}\right)^5\)
\(=\frac{1024}{3125}\)
d) Ta có: \(\left(\frac{121}{64}\right)^2\cdot\left(-\frac{64}{11}\right)^2\)
\(=\frac{121^2}{64^2}\cdot\frac{64^2}{11^2}\)
\(=11^2=121\)
e) Ta có: \(\left[\left(-3\right)^3\right]^3\cdot271:125\)
\(=\left(-27\right)^3\cdot\frac{271}{125}\)
\(=\frac{-5334093}{125}\)
