Given,

The number = 74.

To Find,

The standard form of 74.

Solution,

Before solving the question, let's understand the concept of standard form and the steps involved in writing the standard form of a decimal number.

Standard Form: Standard form refers to any number between 1.0 and 10.0 that can be expressed as a decimal number multiplied by a power of 10.

Steps involved in writing the standard form of any number:

Step1: Move your number after the first non-zero digit from its original position.

Step2: Count the number of digits you moved. We will write this number in standard form as the power of 10.

Step3: If you move the numbers in the left direction, then the power of 10 will be positive.

Now, let's solve the question.

Number is given = 74

Using the first step, we will move the digit,

= 7.4

Using the second step, we will count the number of places we moved the digit.

In this case, we moved the digit to one places

So, It is 10¹.

= 7.4 × 10¹

Using the third step, we moved the digit to the left,

So, the power will be positive,

= 7.4 × 10¹

The standard form of 74 is 7.4 × 10¹.
