Introduction

Scientific notation is a way of expressing very large or very small numbers in a more manageable form. It is commonly used in mathematics, physics, and engineering to simplify calculations and make it easier to understand complex concepts. In this article, we will explore the product of 41 and a large number expressed in scientific notation.

What is Scientific Notation?

Scientific notation is a way of expressing numbers in the form $a \times 10^b$ , where $a$ is a number between 1 and 10, and $b$ is an integer. For example, the number 400 can be expressed in scientific notation as $4 \times 10^2$ . This form makes it easier to perform calculations and compare numbers.

The Product of 41 and a Large Number

The problem asks us to find the product of 41 and a large number expressed in scientific notation. The large number is given as $4.4 \times 10^5$ . To find the product, we need to multiply 41 by $4.4 \times 10^5$ .

Step 1: Multiply 41 by 4.4

First, we multiply 41 by 4.4 to get the product of the two numbers without the scientific notation.

41 × 4.4 = 180.4

Step 2: Multiply by $10^5$

Next, we multiply the result by $10^5$ to get the product in scientific notation.

180.4 × $10^5$ = 180.4 × $10^5$

Step 3: Simplify the Result

To simplify the result, we can express 180.4 as a number between 1 and 10 multiplied by $10^2$ . This gives us:

180.4 = 1.804 × $10^3$

Now, we can multiply this by $10^5$ to get the final result.

1.804 × $10^3$ × $10^5$ = 1.804 × $10^8$

Conclusion

The product of 41 and $4.4 \times 10^5$ expressed in scientific notation is $1.804 \times 10^8$ . This form makes it easier to understand and compare the result with other numbers.
