The number that is raised to a power. In "7^{4}", 7 is the base.
A number times itself times itself. 5 cubed = 5^{3} = 5×5×5 = 125.
A number that, when cubed, is equal to the given number.
The power to which a number is raised; the number of times a number is multiplied. In "7^{4}", 7 has an exponent of 4, and 7 is multiplied 4 times (7×7×7×7).
An exponent in which the numerator is the power to which the number should be taken and the denominator is the root which should be taken.
The sum of two numbers, divided by 2 (sometimes called an average). This yields the number directly between the two numbers.
An exponent that takes the base number to the positive opposite of the exponent (the exponent with the negative sign removed), and places the result in the denominator of a fraction whose numerator is 1.
The square of a whole number. 1, 4, 9, 16, 25, 36, 49, ... are all perfect squares.
To remove all factors that are perfect squares from inside the square root sign and place their square roots outside the sign.
A number times itself. 5 squared = 5^{2} = 5×5 = 25.
A number that, when squared (multiplied by itself), is equal to the given number.
