Answer:
the first term is [tex]5x^4[/tex]
Step-by-step explanation:
We have been given the polynomial [tex]1+6x^2+5x^4+3x^3[/tex]
Arrange this polynomial in descending order. In other words we arrange this polynomial having exponent from greatest to smallest.
Exponents from descending order is given by
4, 3, 2, 0
So, the polynomial when arranged in descending order is given by
[tex]5x^4+3x^3+6x^2+1[/tex]
Therefore, the first term is [tex]5x^4[/tex]
