To determine

To calculate: The number 7.4 in scientific notation.

Explanation

Given Information:

The number is:

24.85

Formula used:

The way to represent either a larger number or smaller number in such a way that it is the product of the number between 1 to 10 and exponent of a power of 10 is called as scientific notation.

Mathematical, representation is:

a×10n

Here, a is any real number between 1 to 10 and n is any integers.

Approach to write a decimal number in scientific notation is as follows:

Step 1: Place a decimal after first non-zero digit while reading the number from left to right.

Step 2: A crate (^) is placed at the original decimal place.

Step 3: Now, if the new decimal point is left to the original decimal point or crate (^), add the exponent of the power of 10 same as the decimal place count between decimal point and the crate.

Step 4: Now, if the new decimal point is left to the original decimal point or crate (^), add the exponent of the power of 10 same as the decimal place count between decimal point and the crate
