### Fac, Frac,. Exponents

Question | Answer |
---|---|

Rules for Divisibility | For 2 the number has to be even. For 3,6,7,9 you add up the sums and if that see if that number is divisible. For 4 the last 2 digits have to be divisible by 4. For 8 the last 3 digits have to be divisible by 8. For 5 the number must end in 5 or 0. |

Factor | One integer is a factor of another nonzero integer if it divides that integer with a remainder of zero. |

Exponents | Exponents show repeated multiplication. |

Power | Powers have bases and exponents. Like 8^6 |

Base | The base of a power is 8 in 8^6 |

Prime Factorization | This is a method of how to find the prime numbers that multiply up to a certain number |

Prime Number | A prime number for example is 5 because no other numbers can be multiplied into it. |

Composite Numbers | A composite number is 10 because it has other factors besides 1 and itself. |

GCF | Greatest Common Factor is when you pick 2 or more numbers for example 10 and 30 you try to find the biggest common factor that goes into both numbers. for 10 and 30 the GCF would be 10. |

Equivalent Fractions | Equivalent fractions have different numbers but the same value. Like 1/4 and 2/8. |

Simplest Form | When something is written in simplest form it is written when it cant be reduced any more. 4/8 would reduced into 1/2 |

Rational Number | A rational number is any number you can write as a quotient a/b of two integers where b is not zero. Integers are rational numbers because they can be written as a/1. |

Power of a power | This is when a exponent is inside parenthesis with another power outside of it. (7^2)^3 This would evaluated as 7^2x3 or 7^6 |

Order Of Operations | P.E.M.D.A.S. parenthesis. powers, multiply, divide, add, subtract |

Variable GCF | A GCF of two or more numbers that contain a variable. |

Find GCF of 78 and 124 | 2 |

12x^2y^5 over 8x^4y^2 | 3y^3 over 2x^2 |

Rational Numbers (examples) | 1, 2, 1.2, 5.5, 0 |

Negative Rational Number (examples) | -1, -2, -5, -1.1 |

4x^3y^5 times 3x^2yz^2 | 12x^5y^6z^2 |

(x^3y^5)^4 | x^12y^20 |

x^0 | 0 |

x^-3 | 1/-3 |

x^-3y^2 over a^2b^-3 | b^3y^2 over a^2x^3 |

Rewrite without fraction bar x^3y^2 over a^2b^3 | x^3y^2a^-2b^-3 |

No zero or negative exponents x^-3y^2z^0 over x^-2y^-3 | y^5 over x |
