**What is Standard form: **A standard form is a way of writing a number that is consistent and recognized by everyone. It makes it easier to communicate and understand numbers. The standard form is also known as scientific notation.

**How to write the number in standard form?**

To write a number in standard form, you need to follow these steps:

-First, identify the digits that will make up your number. This includes all of the digits 0-9.

-Next, determine the value of each digit based on its place value. For example, the digit in the one’s place has a value of 1, the digit in the tens place has a value of 10, and so on.

-Finally, add up the digits to get your final number. For example, if you have a number made up of the digits 1, 2, and 3, you would add them up to get 6. This is your standard form number.

Here, we’ll change a number expanded form into its standard form.

**The number 546 can be written as**

The expanded form of a number is the sum of the place values of each of its digits.

**Write the standard form of:**

(i) 40000 + 6000 + 300 + 10 + 4

= 46314

(ii) 800000 + 30000 + 50 + 2

= 830052

No value is given for the thousands and hundreds place, so we write zeros in these two places.

(iii) 60000 + 700 + 50 + 3

= 60753

No value is given for the thousands, so we write zeros in this place.

(iv) 900000 + 1

= 900001

No value is given for the ten thousands, thousands, hundreds and tens place, so we write zeros in these four places.

(v) 700000 + 500 + 1

= 700501

No value is given for the ten thousands, thousands and tens place, so we write zeros in these three places.

These are the above examples converting the expanded form of numbers to standard form.
