  1. 1. convert scientific notation into a decimal
  2. 6. terms that have the same variable or base
  3. 8. a mathematical statement that shows that two mathematical expressions are equal
  4. 9. _____________ Exponent Rule Any non-zero number raised to the zeroth power is 1. x0 = 1
  5. 10. _____________ Rule The power of a quotient is equal to the power of each term in the numerator and denominator raised individually. (a/b)x = ax/bx
  6. 12. _____________ rules ex. When multiplying with like bases, add the exponents
  7. 16. _____________ Rule To raise a number with an exponent to a power, multiply the exponent times the power. (am)n = am*n
  8. 17. _____________ Property of Equality - states that if both the sides of an equation are multiplied by the same number, the expressions on the both sides of the equation remain equal to each other. ac=cb, then a = b
  9. 20. _____________ notation multiplication problem that multiplies a whole number that is a decimal by 10 with an exponent of 1 thru whichever number
  10. 22. _____________ expression an expression which is made up of variables and constants
  11. 23. _____________ equation in one variable an equation which has a maximum of one variable of order 1
  12. 24. changing the sign of the number and adding it to the original number to get an answer equal to 0
  13. 25. _____________ Rule To find the product of two numbers with the same base, add the exponents. am * an = am + n.

  1. 2. a number that makes the equation true x=2
  2. 3. the operation that undoes what was done by the previous operation
  3. 4. an unknown quantity, often designated by a letter (most often x), that can take on different values in an expression or equation.
  4. 5. _____________ number not perfect squares, non-terminating or non-repeating numbers, numbers that can not be expressed in fraction/ratio form
  5. 7. _____________ Rule To find the quotient of two numbers with the same base, subtract the exponent of the denominator from the exponent of the numerator. am / an = am–n
  6. 11. _____________ Exponent Rule Invert the base to change a negative exponent into a positive. x–n = 1/xn
  7. 13. an algebraic expression to find the value of the expression when the variable is replaced by a given number
  8. 14. _____________ Property of Equality adding the same quantity on both sides of an equation produces equivalent results
  9. 15. _____________ Rule when a product is raised to a power, the result is the product of each factor raised to the power. (ab)x = axbx
  10. 18. Exponent refers to the number of times a number is used in a multiplication problem
  11. 19. _____________ number perfect squares, numbers shown as fractions or ratios, terminating or repeating decimals
  12. 21. _____________ notation a method for expressing large numbers or small numbers as the product of a decimal less than 10 and multiplied by a power of 10.
