To determine

The number $4.02\times {10}^3$ needs to express in the standard form.

Answer to Problem 9.5.5EP

The number $4.02\times {10}^3$ in the standard form is $4020$ .

Explanation of Solution

Given:

  $4.02\times {10}^3$

Concept Used:

To write the very large or very small numbers easily, the standard form is used. To convert a number into standard form decimal point, addition, subtraction, multiplication and division methods are used.

Calculation:

The given number is: $4.02\times {10}^3$

Here the power of $10$ is $3$ . So, multiply the given number with ${10}^3=1000$

  $4.02\times {10}^3=4.02\times 1000=4020$

Hence, the standard form of $4.02\times {10}^3$ is $4020$ .

Conclusion:

Hence, $4.02\times {10}^3=4020$
