\(=\dfrac{3^5}{-\left(0.003\right)^3\cdot0.09}=-10^{11}\)
a,32
b,\(-\frac{1}{10}\)
c,-1000000
d,\(\frac{9}{16}\)
\(\dfrac{\left(0,125\right)^5.\left(2,4\right)^5}{\left(-0,3\right)^5.\left(0.01\right)^3}=\dfrac{\left(0,125\right)^5.\left(-0,3\right)^5.\left(-8\right)^5}{\left(-0,3\right)^5.\left(0.01\right)^3}=\dfrac{\left(0,125\right)^5.\left(-8\right)^5}{\left(0.01\right)^3}=\dfrac{\left(-8.0,125\right)^5}{\left(0.01\right)^3}=\dfrac{-1}{0.000001}=-1000000\)
