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

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

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