Base When a number is raised to a power, the number that is used as a factor is the base. A number produced by raising a base to an exponent. Power Exponential Form Scientific Notation A number is in exponential form when it is written with a base and an exponent. A method for writing a very large or very small number by using powers of 10. The statement is expressed a number greater than or equal to 1 but less then 10 and a product of a power of ten (i.e.: 8.965 x 10-5 or 5.25 x 1018). The positive or non-negative square root of a number. Principal Square Root Radical Significant Digits The symbol used to represent the square root of a number. The digits of a number that express a quantity to some specific degree or accuracy, rounding the last figure up to the next would be 5 or greater. A number raised to the second power. Square A number that has a rational number as its square root.. Perfect Square A number raised to the third power. Cubed Root Rational Numbers A real number that can be expressed as the ratio of two integers with a non-zero denominator. Irrational Numbers A real number that cannot be expressed as the ration of two integers. Term Definition Natural Numbers The set of counting numbers in the real number system. {1, 2, 3, 4, …} Whole Numbers The set of counting numbers and zero in the real number system. {0, 1, 2, 3, …} Integers The set of whole numbers and their opposite in the real number system. {… -3, -2, -1, -, 1, 2, 3, …} A rational or irrational number. Real Numbers Pythagorean Theorem In a right triangle, the square of the length of the hypotenuse is equal to the square of the lengths of the legs (sides). In a right triangle, the sides that includes the right angle. Leg The side opposite the right angle in a right triangle. Hypotenuse
