Question

What is 0.0703 written in scientific notation?​

Answer 1

Answer:

$\large\boxed{0.0703=7.03\times10^{-2}}$

Step-by-step explanation:

The scientific notation:

$a\times10^k$

where

$1\leq a$

We have

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

METHOD 1:

use $a^{-n}=\dfrac{1}{a^n}$

$=7.03:\dfrac{1}{10^{-2}}=7.03\times\dfrac{10^{-2}}{1}=7.03\times10^{-2}$

METHOD 2:

$0.0703=0.0703\times10^0=0\underbrace{.07}_{2\to}03\times10^0=7.03\times10^{0-2}=7.03\times10^{-2}$
