The correct option is C x
Standard Form of a Polynomial:––––––––––––––––––––––––––––––––––––––––
A polynomial is said to be in its standard form, if it is expressed in such a way that the term with the highest degree is placed first, followed by the term which has the next highest degree, and so on.
We are given with a polynomial expression 7x2−x3+x−8x6+4x5.
The highest exponent of this polynomial is 6 and the corresponding term is −8x6.
The second highest exponent is 5 and the corresponding term is 4x5.
The third highest exponent is 3 and the corresponding term is −x3.
The fourth highest exponent is 2 and the corresponding term is 7x2.
The fifth highest exponent is 1 and the corresponding term is x.
The polynomial expression 7x2−x3+x−8x6+4x5 when written in standard form would be:
−8x6+4x5−x3+7x2+x
The last term of the polynomial expression 7x2−x3+x−8x6+4x5 (i.e., fifth term) when written in standard form would be x. Therefore, option (c.) is the correct answer.
