Answer 1

add up the exponents for each term

the degree will be equal to the largest sum

Answer 2

Will it be 11s8t10+21

Answer 3

no sry I should have clarified

Answer 4

For the first term 2st^4, the exponents are 1 and 4. So the sum of the exponents is 1+4 = 5

For the second term s^2t^2, the exponents are 2 and 2. The sum of the exponents is 2+2 = 4

For the third term, the sum of the exponents is 5+1 = 6

The degree is equal to the largest sum

Answer 5

So will it be 2st5+st4+st6+21

Answer 6

No the degree is simply a number

Answer 7
