Find 4.5×10^7 over 1.5×10^-8 . write answer in scientific notation.
Sati [7]

Answer:

\large\boxed{\dfrac{4.5\times10^7}{1.5\times10^{-8}}=3\times10^{15}}

Step-by-step explanation:

The scientific notation:

a\times10^k\ \text{where}\ 1\leq a

We have:

\dfrac{4.5\times10^7}{1.5\times10^{-8}}=\dfrac{4.5}{1.5}\times\dfrac{10^7}{10^{-8}}

Use

\dfrac{a^n}{a^m}=a^{n-m}

=3\times10^{7-(-8)}=3\times10^{7+8}=3\times10^{15}
