Answer:
[tex]\large\boxed{\dfrac{4.5\times10^7}{1.5\times10^{-8}}=3\times10^{15}}[/tex]
Step-by-step explanation:
The scientific notation:
[tex]a\times10^k\ \text{where}\ 1\leq a<10\ \text{and}\ k\in\mathbb{Z}[/tex]
We have:
[tex]\dfrac{4.5\times10^7}{1.5\times10^{-8}}=\dfrac{4.5}{1.5}\times\dfrac{10^7}{10^{-8}}[/tex]
Use
[tex]\dfrac{a^n}{a^m}=a^{n-m}[/tex]
[tex]=3\times10^{7-(-8)}=3\times10^{7+8}=3\times10^{15}[/tex]
