What is the coefficient of 4 x 450?
The coefficient of the expression ( 4 \times 450 ) is 4. In this context, the coefficient refers to the numerical factor that multiplies the variable or term—in this case, the number 4 is the coefficient of the product. The overall product equals 1800, but the coefficient remains 4.
What is 3v plus 15v - 11v2 - 14v plus 5v2 plus 8v3 - 4v3?
Assuming that the numbers immediately succeeding each "v" in the expression are intended to be exponents, in this type of problem only the coefficients of those terms with the same exponents can be added. Therefore in the sum, the coefficient of "v" will be (3 + 15 - 14) = 4; the coefficient of "v2" will be (-11 + 5) = -6; and the coefficient of "v3" will be (8 - 4) = 4. The final answer is therefore 4 v3 - 6 v2 + 4 v.
