Answer:
[tex]\large\boxed{0.0703=7.03\times10^{-2}}[/tex]
Step-by-step explanation:
The scientific notation:
[tex]a\times10^k[/tex]
where
[tex]1\leq a<10,\ k\in\mathbb{Z}[/tex]
We have
[tex]0.0703=7.03:100=7.03:10^2[/tex]
METHOD 1:
use [tex]a^{-n}=\dfrac{1}{a^n}[/tex]
[tex]=7.03:\dfrac{1}{10^{-2}}=7.03\times\dfrac{10^{-2}}{1}=7.03\times10^{-2}[/tex]
METHOD 2:
[tex]0.0703=0.0703\times10^0=0\underbrace{.07}_{2\to}03\times10^0=7.03\times10^{0-2}=7.03\times10^{-2}[/tex]
