Explanation:

To find : What is thirty-four million plus two hundred fifty-six thousand times four hundred?

Solution :

First we write the words in number form,

Thirty-four million - 34,000,000

Two hundred fifty-six thousand - 256000

Four hundred - 400

Two hundred fifty-six thousand times four hundred -
`256000* 400=102400000`

Now, We have to add

Thirty-four million plus two hundred fifty-six thousand times four hundred

i.e. 34000000+102400000 = 136400000

In scientific notation,

`136400000=1.364* 10^8`
