| Question | Answer |
|---|---|
| 2 | Even number |
| 3 | add all digits and that must be divisible by three |
| 4 | last two digits divisble |
| 5 | number ends in 0 or a 5 |
| 6 | divisible by both two and three |
| 7 | divide by seven |
| 8 | last three digits add up and divide |
| 9 | add up each digit and that must be divisible by nine |
| ten | ends in 0 |
| Factors | A number that divides a number with zero left over |
| Order of operations | PEMDAS |
| Exponent | the number above a number telling how many times a number is to be multiplied by itself |
| Base | The repeated factor of a number in exponential form |
| Power | The exponent |
| (-3)^2 is also known as | (-3) x (-3) |
| -3^2 is also known as | -3 x -3 |
| Prime number | Number that has no factors |
| Composite Number | Has factors |
| GCF | Greatest Common Factor |
| x^2 x y^5, xy^3 | (x) x (y^3) |
| prime factorization 120 | (2^3),( 3), (5) |
| Prime Factorization of 78 and 124 | Find factors of both^ and take what is in common and multiply it |
| 12, x^2, y^5/8, x^4, y^2= | 3, 7^3/2, x^2 |
| Rational Number | A number that can be put into a fraction |
| Rational number | 5, 5/1 1/5 |
| Negative Rational Numbers | if number is -7 and is put 1/-7 move the negative to the top |
| 4x^3 y^5 * 3x^2 y z^2= | 12 x^12 y^5 |
| (x^3y^5)^4= | x^12 y^20 multiply exponent out of perenthesis and the one from inside the perenthesis |
| x^0= | x (number of base) |
| (x)^-3 | (-x) x (-x) x (-x) multiply ex but negative |
| x^-3, y^2/a^2, b^-3 | y^2, b^3/ a^2, x^3 (negatives move to opposite side of the division bar |
| x^3, y^2/ a^2, b^3 | x^3, y^2, a^-2, b^-3 if the numbers move from bottom to top the exponents become negative |
| x^-3, y^2 z^0/ X^-2, y^-3 = | x^2, y^5/x^3 |
