Answer 1

exercise #1
here the degree of the polynomial is given by the exponent of the monomial \(x^{10}\)

Answer 2

exerxise #2
here we have no letteral part, and that means all exponents are equal to zero, so what can you conclude?

Answer 3

exercise #3
for sum you have to compute \(4-9=...?\) as coefficient of \(x^{10}\)
for difference you have to compute \(4-(-9)=...?\)as coefficient of \(x^{10}\)

Answer 4

exercise #4
for sum you have to compute \(7-10=...?\) as coefficient of \(t^5\)
for difference you have to compute \(7-(-10)=...?\)as coefficient of \(t^5\)
