Question

What is 0.0703 written in scientific notation?
​

Answer 1

`\large\boxed{0.0703=7.03*10^(-2)}`

Explanation:

The scientific notation:

`a*10^k`

where

`1\leq a<10,\ k\in\mathbb{Z}`

We have

`0.0703=7.03:100=7.03:10^2`

METHOD 1:

use
`a^(-n)=(1)/(a^n)`

`=7.03:(1)/(10^(-2))=7.03*(10^(-2))/(1)=7.03*10^(-2)`

METHOD 2:

`0.0703=0.0703*10^0=0\underbrace{.07}_(2\to)03*10^0=7.03*10^(0-2)=7.03*10^(-2)`
