What is the 5th term of binomial expansion?

Explanation: The fifth term is the middle term of nine, with coefficient given by all the ways of choosing 4 items out of 8 , namely the ways of choosing 4 a ‘s out of 8 binomial factors.

What is the coefficient of x8y9?

What is the coefficient of x8y9? )35(−2)13 = −17055940608 Meanwhile, 8 + 9 = 18, so no terms of the form cx8y9 arise in the binomial expansion, so in other words the coefficient of x8y9 is 0. ). Let S be a set of size n.

How do you find the end of a 5th term?

pth term from the end =(n-p+2) th term from the beginning. ∴5th term from the end =(12-5)+2)th=9 th term.

What is the coefficient of a term?

A coefficient (in general) is any of the factors of a term relative to a given factor of the term. In the term -5x2y, the coefficient of “y” is -5×2. In the term -5x2y, the coefficient of “x2” is -5y. In the term -5x2y, the coefficient of “x2y” is -5.

What is the 5th term at the end of AP 2 7 12?

Consider the AP 47, 42,…, 12, 7, 2. Hence, the 5th term from the end of the given AP is 27.

Which is the fifth of the AP 7 13?

142 is the answer.

What is the coefficient of XY?

1
Coefficient of xy in the term -xy is 1.

What is the coefficient of 5×2 in this equation?

In the first term 5x 2, x is the variable and as we know that a coefficient always comes with the variable, the coefficient is 5. In the second term 2y, y is the variable, so the coefficient is 2. In the third term, 7 is known as the constant. A numerical coefficient is a number which is the multiplier of the variables in a term.

What is the numerical coefficient of the 5th term?

The numerical coefficient of the 5th term is 126,720. View Solution:

What is the meaning of coefficient in math?

Coefficient. In mathematics, a coefficient is an integer which is multiplied with the variable of a single term or the terms of a polynomial. It is usually a number, but sometimes may be replaced by a letter in an expression. For example, in the expression: ax 2 + bx + c, x is the variable and ‘a’ and ‘b’ are the coefficients.

What is the coefficient of 2y in the second term?

In the second term 2y, y is the variable, so the coefficient is 2. In the third term, 7 is known as the constant. A numerical coefficient is a number that is the multiplier of the variables in a term. For example, 3 is the numerical coefficient of the term 3mn.
