  1. 3. A number expressible in the form a/b or -a/b for some fraction a/b it include the integers.
  2. 5. a multiplication expression raised, as a whole, to a power
  3. 6. A number that relates two quantities or measures within a given situation in a multiplicative relationship
  4. 8. A number made by squaring a whole number.
  5. 9. The ratio of the length in a drawing (or model) to the length on the real thing
  6. 11. A fraction in which the numerator and/or the denominator contain fractions. A fraction, A/B where A and/or B are fractions (B ≠ 0)
  7. 12. The type of number we normally use, such as 1, 15.82, −0.1, 3/4; includes Positive or negative, large or small, whole numbers, fractions or decimal numbers
  8. 16. is a number whose square is 𝑦 ∙ 𝑦.
  9. 17. If the variable has an exponent, then you multiply the power of the expression by the power of the exponent.
  10. 18. a number that says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number.
  11. 20. The symbol is √
  12. 21. the multiplicative inverse of the base raised to the positive opposite of the power
  13. 22. A number that cannot be represented as a fraction.

  1. 1. when dividing two powers with the same base, we subtract the exponents.
  2. 2. you are taking an expression that is already raised to an exponent and raising it to yet another exponent
  3. 4. The cube root of a number is a special value that, when used in a multiplication three times, gives that number.
  4. 6. the ratio between two related quantities in different units.
  5. 7. A number made by cubing a whole number.
  6. 10. when multiplying two powers with the same base, we add the exponents.
  7. 13. an expression containing a square root.
  8. 14. A number to be raised to a power, denoted by an exponent. Also, a set of digits used to represent numbers
  9. 15. says that two ratios (or fractions) are equal.
  10. 16. 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.
  11. 19. A symbol written above and to the right of a mathematical expression to indicate how many times the mathematical expression (base) should be multiplied by itself.
