| Question | Answer |
|---|---|
| base | One of two parallel congruent faces of a prism. |
| cube root | One of three equal factors of a number. If a3 = b, then a is the cube root of b. The cube root of 64 is 4 since 43 = 64. |
| exponet | In a power, the number of times the base is used as a factor. In 10 3, the exponent is 3. |
| irrational number | A number that cannot be expressed as the the quotient a/b, where a and b are integers and b 0. |
| monomail | A number, a variable, or a product of a number and one or more variables. |
| perfect cube | A rational number whose cube root is a whole number. 27 is a perfect cube because its cube root is 3. |
| perfect square | A rational number whose square root is a whole number. 25 is a perfect square because its square root is 5. |
| power | A product of repeated factors using an exponent and a base. The power 73 is read seven n to the third power, or seven cubed. |
| radical sign | The symbol used to indicate a positive square root. |
| rational number | Numbers that can be written as the ratio of two integers in which the denominator is not zero. All integers, fractions, mixed numbers, and percents are rational numbers. |
| repeating decimal | Decimal form of a rational number. |
| scientific notation | A compact way of writing numbers with absolute values that are very large or very small. In scientific notation , 5,500 is 5.5 10/3. |
| square root | One of the two equal factors of a number. if a/2 = b, then a is the square root of b. A square root of 144 is 12 since 12/2 = 144. |
| terminating decimal | A repeating decimal where the repeating digit is 0. |
