Question

6.6x10^5 / 3.3x10^15

Answer 1

$\frac{6.6\times10^5}{3.3\times10^{15}}$

We can use the following property of exponents:

$\begin{gathered} x^y\cdot y^z=x^{y+z} \\ a^{-x}=\frac{1}{a^x} \end{gathered}$

So:

$\frac{6.6\times10^5}{3.3\times10^{15}}=\frac{6.6}{3.3}\times10^{5-15}=2\times10^{-10}$

Answer:

2x10⁻¹⁰
