Then you should divide it by 3 to find the other factor. If the sum of the digits is not divisible by 3, then the original number is also not divisible by any other multiple of 3 such as 6, 9, 12, 15, 18, etc. Next, test if it is divisible by 5… For 5: If the number you are factoring ends in either 5 or 0, then it is divisible by 5. If doesn’t end in 5 or 0, then it is also not divisible by any other multiple of 5. Next, test if it is divisible by 7… For 7 and higher: Take the number you are attempting to prime factor, divide it by 7, and analyze the quotient.
Remember… when multiplying factors (with a common base) with exponents, you do not multiply their exponents; this is a frequently made mistake. Dividing Bases With Exponents When dividing numbers or variables with a common base, keep the base the same and subtract the exponent of the denominator from the exponent in the numerator. Remember to keep the signs of the exponents. You may subtract a negative exponent, yielding a positive exponent. You may also get a negative number as the exponent, which is fine, but in the final, simplified form of your answer, you shouldn’t leave an exponent negative.
It is worth noting here that the equation of the y-axis is “x = 0” because it intersects the x-axis at “x = 0”. Another common mistake is to use “zero” and “no-slope” interchangeably, but they are significantly different. A vertical line literally has no slope (not even zero). ” For more on this, see: When x1 = x2, and: What Does "Undefined" Mean? The concept of horizontal and vertical lines (and their equations) is something that students often have trouble with at first, perhaps because the books seem to give them a small section displaced from the more emphasized diagonal lines (which is just inevitable).
