Answer:

The quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$ is: $\mathbf{3.3\times 10^{-4}}$

Step-by-step explanation:

We need to find quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$

We know that $10^0=1$

Now solving:

$\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033$

Writing it in scientific notation

$0.00033\\=3.3\times10^{-4}$

So, the quotient of: $\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}$ is: $\mathbf{3.3\times 10^{-4}}$
