Answer:
2. 9
3.12 p^4 - 1/2 p^3 -8p^2 + 2p
Explanation:
The degree of the polynomial is found by taking the number of the highest exponent. We add the exponent when there is more than one variable in a term
5m^6n^3 = degree (6+3) = 9
3m^4n^2 = degree (4+2) = 6
So the polynomial is degree 9
Standard from is written from largest exponent to smallest exponent
12 p^4 - 1/2 p^3 -8p^2 + 2p
