Answer 2

The given number 12750000, expressed in standard form, will be $1.2 \times 10^{7} .$

Given,

The number:

12750000.

To find,

The given number expressed in standard form.

Solution,

A standard form of a given large number, in mathematics, is a method or way to represent the number, in such a way that it is written in the form of

$a \times 10^{b} \hfill ...(1)$

Where,

a = a real number such that 1 < a < 10, and

b = an integer.

Here, the given number is

12750000.

So, we need to move the decimal point to the immediate right of 1.

It means the decimal point will be required to move 7 places toward the left.

Now, we know, from the rules of writing numbers in standard form, that

• when the decimal point moves toward the left, we have the exponent of 10 (that is, 'b' in eq. 1 above), as positive,
• while, if the decimal point moves toward the right, we have the exponent of 10 (that is, 'b' in eq. 1 above), as negative.

So, the given number can be written as

$1.2 \times 10^{7} .$

Therefore, the given number 12750000, expressed in standard form, will be $1.2 \times 10^{7} .$
