\(=\dfrac{\left(0.125\cdot2.4\right)^5}{\left(-0.3\cdot0.01\right)^3\cdot\left(-0.3\right)^2}=\dfrac{0.3^5}{0.3^2\cdot\left(-0.003\right)^3}=\dfrac{0.3^3}{-0.003^3}=-1000000\)
a,32
b,\(-\frac{1}{10}\)
c,-1000000
d,\(\frac{9}{16}\)
Có \(\left(-2\dfrac{3}{4}+\dfrac{1}{2}\right)^2\)=\(\left(\dfrac{-5}{4}+\dfrac{2}{4}\right)^2\)=\(\left(\dfrac{-3}{4}\right)^2\)=\(\dfrac{\left(-3\right)^2}{4^2}=\dfrac{9}{16}\)
Có \(\dfrac{\left(0,125\right)^5.\left(2,4\right)^5}{\left(-0,3\right)^5.\left(0,01\right)^3}=\dfrac{\left(0,125.2,4\right)^5}{\left(-0,3\right)^5.\left(0,01\right)^3}=\dfrac{\left(0,3\right)^5}{\left(-0.3\right)^5.\left(0,01\right)^3}=\dfrac{1}{-1.\left(0,01\right)^3}=\dfrac{1}{-\left(0,01\right)^3}\)
\(=\dfrac{3^5}{-\left(0.003\right)^3\cdot0.09}=-10^{11}\)
