A decimal power refers to the exponent or power of 10 that is used to express a decimal number. It is also known as scientific notation or standard form.
To calculate the decimal power, count the number of digits after the decimal point in the original number. This will be the exponent of 10. For example, if the original number is 0.005, the decimal power would be 10-3.
To convert a decimal number to decimal power, move the decimal point to the left or right until there is only one non-zero digit to the left of the decimal point. The number of places you move the decimal point will be the exponent of 10. If the decimal point is moved to the left, the exponent will be positive. If the decimal point is moved to the right, the exponent will be negative.
To calculate negative decimal powers, use the formula 10-n where n is the absolute value of the exponent. For example, 10-3 is equivalent to 1/103, which equals 0.001.
Decimal power is used in scientific notation because it allows for easier representation of very large or very small numbers. By using powers of 10, these numbers can be expressed in a more compact form, making them easier to work with and compare.
