for the polynomial below, what is the coefficient of the term with the power of 3[tex] {x}^{2} + \frac{1}{3} {x}^{4} + 6x + 5[/tex]

We have the polynomial:
[tex]x^3+\frac{1}{3}x^4+6x+5[/tex]The coeficient of the term with the power of 3 is 1, because we have:
[tex]x^3=1\cdot x^3[/tex]The correct answer is B.
