To find the fourth term of the binomial expression ((2x + 5)^5), we can use the Binomial Theorem, which states that the (k)-th term in the expansion of ((a + b)^n) is given by (T_{k+1} = \binom{n}{k} a^{n-k} b^k). For our expression, (a = 2x), (b = 5), and (n = 5). The fourth term corresponds to (k = 3), so we calculate:
[ T_4 = \binom{5}{3} (2x)^{5-3} (5)^3 = \binom{5}{3} (2x)^{2} (125) = 10 \cdot 4x^2 \cdot 125 = 5000x^2. ]
Thus, the fourth term is (5000x^2).

What does binomial mean in math?
Well a binomial is a mathematical expression with two terms. ex. (2x+5) {2x is one term 5 is the other}, (5x+9) {5x is one term 9 is the other} terms are seperated by + or - signs only.
What is the algebraic expression for add one - fourth to 2 times x?
1/4 + 2x
Which is a constant in this expression 7 2x?
In the expression (7 + 2x), the constant is (7). A constant is a term that does not change and does not contain any variables, while (2x) is a term that depends on the variable (x). Therefore, (7) remains the same regardless of the value of (x).
What is -2x-2x4?
The expression (-2x - 2x^4) combines two terms: (-2x) and (-2x^4). It is a polynomial in terms of (x), where (-2x^4) is the dominant term due to its higher degree. This expression cannot be simplified further without knowing the value of (x).

Is 3X cubed minus 2X squared a binomial?
No, it isn't. You can express 3x3-2x2 as 3x3-2x2+0x+0, so it actually has four terms. The definition of a binomial is an expression in the form Ax+b, where A and b are constants, so 3x3-2x2 is not a binomial. It is actually a quartomial.
What is the meaning of term in mathematics?
It's not very easy to tell you the meaning but an example of a term would be: 2x + 5, the 2x and the 5 are the terms of the expression. I hoep that helped.
Can you give one example of a binomial?
One example of a binomial is (x + 2).
