1.
Select all (and only) monomials of degree 7.
HINT: Make sure that the sum of all exponents of variables in the term is 7. But also make sure the term is actually a monomial!

Question 2
2.
Reorganize this polyexpression so it is in "standard form". This means- The monomial with the highest degree should come first, with every next monomial of equal or lesser degree.
- Whenever possible, order the variable factors within a monomial alphabetically.
9x^{2}+x^{4}+128+12x-5x^{3}
