Answer 2

The number k is a real number such that 1 ≤ |k| < 10

Given:

The standard form of a big number or very small number is  $k \times 10^{m}$

Where m is an integer  

To find:

Choose one option

a) 1< k < 10  b) 1 < k ≤ 10  c) 1 ≤ k <10  d) 1 ≤ k ≤ 10  

Solution:

Complete Question:

A number is said to be in the standard form when it is written as k × 10ⁿ where n is an integer and:

a) 1< k < 10  b) 1 < k ≤ 10  c) 1 ≤ k <10  d) 1 ≤ k ≤ 10  

Let's know about the Standard form

Standard form is a way of expressing numbers that makes it easier to compare and work with numbers of vastly different magnitudes.  

It involves writing a number as a×10ᵇ where a is a real number between 1 and 10, and b is an integer.

For example,

The number 543210 can be written in standard form as 5.4321 × 10⁵,  

Here a = 5.4321 can't be less than 1 and it should be lies between 1 to 10

Here we have the standard form of a number is $k \times 10^{m}$

From the above explanations

The number k will be a real number such that 1 ≤ |k| < 10 and is expressed in decimal notation without any scientific notation.

Therefore,

The number k is a real number such that 1 ≤ |k| < 10
