1: \(=4^4\cdot\left(0.25\right)^4\cdot\left(\dfrac{1}{4}\right)^2=\dfrac{1}{16}\)
2: \(=\left(0.5\right)^4\cdot2^4\cdot2^4=16\)
3: \(=\left(-0.125\right)^7\cdot8^7\cdot8^3=-512\)
4: \(=0.1^7\cdot10^7\cdot10^6=1000000\)
5: \(=\left(-2\right)^{13}\cdot2^8=-2^{21}\)
6: \(=\left(-3\right)^7\cdot\left(-3\right)^4=\left(-3\right)^{11}\)
