Answer 2

Answer:

$136400000=1.364\times 10^8$

Step-by-step 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 - $256000\times 400=102400000$

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,

$136400000=1.364\times 10^8$
