=====================================================

Scientific notation is a way of expressing very large or very small numbers in a more manageable form. It involves expressing a number as a product of a number between 1 and 10 and a power of 10. In this article, we will learn how to write the number 0.000000000009256 in scientific notation.

What is Scientific Notation?

Scientific notation is a way of expressing numbers in the form a × 10^n, where a is a number between 1 and 10, and n is an integer. This notation is commonly used in science and engineering to express very large or very small numbers in a more compact and manageable form.

Example of Scientific Notation

Expressing Large Numbers

For example, the number 456,789,012 can be expressed in scientific notation as 4.56789012 × 10^8.

Expressing Small Numbers

Similarly, the number 0.000456 can be expressed in scientific notation as 4.56 × 10^-4.

Writing the Number in Scientific Notation

Now, let's apply the concept of scientific notation to the number 0.000000000009256. To write this number in scientific notation, we need to move the decimal point to the right until we have a number between 1 and 10.

Moving the Decimal Point

Counting the Number of Places

We need to move the decimal point 10 places to the right to get a number between 1 and 10.

Writing the Number in Scientific Notation

The Number Between 1 and 10

The number 0.000000000009256 becomes 9.256 × 10^-10 when we move the decimal point 10 places to the right.

Understanding the Exponent

The exponent -10 in the scientific notation 9.256 × 10^-10 indicates that we moved the decimal point 10 places to the right. This means that the number 0.000000000009256 is 10^-10 times smaller than the number 9.256.

Understanding the Sign of the Exponent

Positive and Negative Exponents

If the exponent is positive, it means that we moved the decimal point to the right. If the exponent is negative, it means that we moved the decimal point to the left.

Conclusion

In conclusion, the number 0.000000000009256 can be written in scientific notation as 9.256 × 10^-10. This notation is a more compact and manageable way of expressing very small numbers.
