Final answer:
To convert the scientific notation 9 x 10^-9 to standard form, you move the decimal point 9 places to the left, resulting in a standard form of 0.000000009.
Step-by-step explanation:
The question is asking to convert the number 9 x 10^-9 into 'normal' or 'standard' form. This form is also known as scientific notation and is a way of expressing very large or very small numbers in a condensed format. In scientific notation, a number is written as the product of two factors: a decimal greater than or equal to 1 and less than 10, and an integer power of 10.
To convert 9 x 10^-9 to standard form, you simply move the decimal point 9 places to the left because the exponent is -9. This will give you the number 0.000000009
