Question

positive integer.
To write 5,000,000,000 in this form, we may take-
and
n = 9
k = 5
and
n = 8
or
k = 50
k = 500
or
and
n = 7
etc.
But, the first form, where 1 Sk< 10 is called the standard form.
From the above example, we conclude that a given number can be written in the form kx
where n is some integer and k is a terminating decimal lying between 1 and 10. i.e. 1 sk<1
The examples given above show that the exponential notation helps us in writing
numbers. In the same way, we can write small numbers also with the help of expone
notation.
Let us take an example to illustrate the point. To write 0.000021 in the form k x 10", w
sk < 10 we can write
0.000021 =
21
1000000
= 21 x 10-6 = 2.1 x 10-5
Example 17: Write the following numbers in the form k x 10" where 1 sk < 10 and n
integer​
