Question

Add and find the degree of the following expressions.

(3m²n + 4pq²) and (5nm² – 2q²p)

Answer 1

(3m²n + 4pq²) and (5nm² – 2q²p)

This can be written as (3m²n + 4pq²) + (5nm² – 2q²p)

Grouping the like terms, we get

(3m²n + 5m²n) + (4pq² – 2pq²)

= m²n(3 + 5) + pq²(4 – 2)

= 8m²n + 2pq²

Thus degree of the expression is 3.
