WebThe divisibility rule of 5 states that if the digit on the units place, that is, the last digit of a given number is 5 or 0, then such a number is divisible by 5. For example, in 39865, the last digit is 5, hence, the number is completely divisible by 5. Similarly, in 3780, the last digit is 0, therefore, 3780 is considered to be divisible by 5. Web2.

WebThe Remainder Theorem for polynomials an application of Euclidean division on polynomials. Let’s explain it closer… When we divide any polynomial f(x) by a linear polynomial $ (x – c)$ we get another polynomial: $ f (x) = (x – c) q(x) + r$ The point of this theorem is realizing what this remainder r really is. WebJan 25, 2024 · What is the divisibility rule for $13$? Ans: To test whether a number is divisible by $13$, the last digit is multiplied by $4$ and added to the remaining number until we get a two-digit number. If the two-digit number is divisible by $13$, then the given number is also divisible by $13$.
