scientific notation

0.0000000005

5 x 10(-9)

Online, "*" is used to indicate multiplication and "^" is used to indicate an exponent.

5 * 10^(-10)

You had to move the decimal point 10 places.

To express the number 0.0000000005 in scientific notation, follow these steps:

Step 1: Count the number of decimal places in the original number. In this case, there are 10 decimal places.

Step 2: Move the decimal point to the right, until there is only one non-zero digit to the left of the decimal point. In this case, we need to move the decimal point 9 places to the right.

Step 3: Since we moved the decimal point to the right, we need to decrease the exponent by the same number of places we moved the decimal point. In this case, we need to decrease the exponent by 9.

Step 4: Write the number in the form a × 10^b, where "a" is the non-zero digit and "b" is the new exponent. In this case, the number can be written as 5 × 10^(-9).

Therefore, the number 0.0000000005 can be expressed in scientific notation as 5 × 10^(-9).

Scientific notation is a way to represent very large or very small numbers using a combination of a decimal number and a power of ten. In this case, the number 0.0000000005 can be expressed in scientific notation as 5 x 10^(-9).

To convert the number to scientific notation, follow these steps:

1. Start by moving the decimal point to the right or left until there is only one nonzero digit to the left of the decimal point. In this case, we need to move the decimal point 9 places to the right, resulting in the number 5.

2. Count the number of places you moved the decimal point. In this case, we moved it 9 places to the right, so the exponent of 10 will be -9.

3. Write the number as a decimal (5) multiplied by 10 raised to the power of the exponent (-9). The exponent is negative in this case since we moved the decimal point to the right. So, 0.0000000005 can be written as 5 x 10^(-9).

This way of representing the number in scientific notation makes it easier to work with and understand very large or small numbers.
