Answer :
Using polynomial concepts, it is found that the sorting of the polynomial expressions from least to greatest based on their degree is given by: I, III, II, IV.
What is the degree of a polynomial?
The degree of a polynomial is given by it's largest exponent.
In this problem, the polynomials are given by:
- I: x + 2xyz.
- II: 9x³y².
- III: 18x² + 5ab - 6y
- IV: [tex]4x^4 + 3x^2 - x - 4[/tex]
Hence, the respective degrees are: 1, 3, 2, 4, and the ordering from least to greatest is: I, III, II, IV.
