What is two hundred three and four hundred three thousandths in standard form?
svetoff [14.1K]

Answer:

2.03403 * 10^2

Step-by-step explanation:

Here, we want to write the given number in standard form

Firstly, we need to write the number in the normal form;

Mathematically, that will be;

203.403

Now, to write in standard form, we move the zero to the back of the first non-zero digit which is 2

What we have in this case will be:

2.03403

How many times did we move the decimal point?

The decimal point was moved two times

So, what we have is that the number two will become a power of 10

So therefore, we have it that;

2.03403 * 10^2

Kindly note that if the movement was to the left, the power becomes a negative number on 10
