Chapter 4 F,F,E
factors, fractions, and exponents
| Question | Answer |
|---|---|
| Rules for Divisibility | to find out if a number is divisible by another number |
| Factors | digits that a number can divided by |
| Order of Operations | PEMDAS perenthesis;exponents;multiply;divide;add;subtract |
| Exponent | tells you how many times you multiply the base number by itself |
| Base | positive or negative integer that may have an exponent above it |
| Power | small number above the base number |
| (-3)sq. means | (-3)(-3) |
| -3sq. means | -3 x -3 |
| Prime Numbers | are only divisible by one and themselves |
| Composite Numbers | divisible by more than one and themselves |
| GCF | greatest common factor |
| Variable GCF | example = X²Y⁵ |
| Prime Factorization | 120 ^ 12 10 ^ ^ 3 4 5 2 ^ 2 2 |
| Finding Prime Factorization Using GCF | find the factors of the number and then find the factors of the factors until you have all prime numbers |
| Simplifying Variable Expressions | simplify the numbers and subtract the exponents from the like variables |
| Rational Numbers | 2/1 4/1 |
| Negative Rational Numbers | always have the negative sign next to the divisibility line or have it next to the numerator |
| 4x³y⁵ ・3x²yz² | 7x⁵y⁶z² |
| (x³y⁵)⁴ | x¹²y²⁰ |
| x⁰ | 0 |
| x⁻³ | -x・-x・-x |
| x⁻³y²/a² | |
| x³y²/a²b³ | x³y²a²b³ |
| x⁻³y²z⁰/x⁻²y⁻³ | y⁵x²/x³ |
