Step-by-step explanation:

We use Standard form to expresss a very large or very small numberc in the product of a decimal form of number [generally between 1 and 10] and powers of ten.

For example : Thirty seven thousand four hundred thirty can be written as 37,430 or it can be written as $3.743\times10^4$.

1. Three hundred seventy-two thousands

= 372,000

$=3.72\times10^5$

2. six nine hundredths

$0.69=\dfrac{69}{100}=6.9\times10^{-1}$

3. Five thousand, three hundred one and ninety six thousandths

= 5,301. 96

$= 5.30196\times10^{3}$
