Answer : It has 3 terms and a degree of 10.
[tex] 5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7 [/tex]
Simplify the expression
[tex] 5s^6t^2 - 8s^6t^2 + 6st^9 - 6t^7 [/tex]
Combine like terms
[tex] - 3s^6t^2 + 6st^9 - 6t^7 [/tex]
To find degree we add the exponents 's' and 't' of each term
[tex] - 3s^6t^2 --> degree = 8 [/tex]
[tex] 6st^9 --> degree = 10 [/tex] ( 's' has exponent 1)
[tex]- 6t^7 --> degree = 7 [/tex]
Simplified expression is [tex] - 3s^6t^2 + 6st^9 - 6t^7 [/tex]
Highest degree is 10
