the product of a multiplication when a number is being multiplied by itself = 6^2 = 6x6=36
the amount of times a number is multiplied by itself in a power ex. 6^2 it is the 6 the number that is being multiplied by itself in a power ex. 6^2 it is the 2 using powers of 10 to represent large and small numbers ex. 4.5 x 10^3 the regular way to write a number ex. 4500 the product when the exponent is 2 in a power the product when the exponent is 3 in a power when the divisor and quotient of a division are the same 
Key Concepts:
Powers: The representation of a product using exponents and bases, when the base is multiplied by itself.
Square Numbers: The number we get after multiplying an integer (not a fraction) by itself. Example: 4 × 4 = 16, so 16 is a square number. We square a number when the exponent of a power is 2.
Cube Numbers: The result of using a whole number in a multiplication three times. Example: 4 × 4 × 4 = 64, so 64 is a cube number. We square a number when the exponent of a power is 3.
Square Roots: For square roots, find the "reverse" of a square. The square root symbol (√, also called a "radical" symbol) means basically the "opposite" of the 2 symbol. When you see a radical, you want to ask yourself, "what number can multiply by itself to give the number under the radical?" For instance, if you see √(9), you want to find the number that can be squared to make nine. In this case, the answer is three, because 32= 9.
Scientific Notation: Where a number is written in two parts: First: just the digits (with the decimal point placed after the first digit.) Followed by: ×10 to a power that will put the decimal point back where it should be.
To convert a number from scientific notation, you move the decimal over so that you have a single digit to the left of the decimal (ones place.) Count the number of decimal places you moved it, and that becomes the exponent on the ten.
