What is scientific notation?

Back

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It is written as a product of a number (between 1 and 10) and a power of 10.

Front

How do you convert a number from scientific notation to standard form?

Back

To convert a number from scientific notation to standard form, multiply the coefficient by 10 raised to the power indicated. For example, 2.08 x 10^2 = 208.

What is the standard form of 6.47 x 10^11?

Back

The standard form of 6.47 x 10^11 is 64700000000.

Front

How do you convert a decimal to a percent?

Back

To convert a decimal to a percent, multiply the decimal by 100 and add a percent sign. For example, 0.384 x 100 = 38.4%.

Front

What is the value of 10^0?

Back

The value of 10^0 is 1.

Front

How do you write a large number in scientific notation?

Back

To write a large number in scientific notation, identify the first non-zero digit, place the decimal after it, and count the number of places the decimal has moved to determine the exponent of 10. For example, 52,300,000 is written as 5.23 x 10^7.

Front

What is the purpose of using scientific notation?

Back

The purpose of using scientific notation is to simplify the representation of very large or very small numbers, making them easier to read, write, and calculate.

Front

How many zeros are in the number 6.47 x 10^11 when written in standard form?

Back

There are 9 zeros in the number 6.47 x 10^11 when written in standard form.

Front

What is the process to convert a number in standard form to scientific notation?

Back

To convert a number in standard form to scientific notation, move the decimal point to the right of the first non-zero digit and count the number of places moved. This count becomes the exponent of 10.

Front

What is the significance of the exponent in scientific notation?

Back

The exponent in scientific notation indicates how many places the decimal point has been moved. A positive exponent indicates a large number, while a negative exponent indicates a small number.
