Answer:
The answer to your question is: (–5)² • a³ • (m + 3)²
Explanation:
Your problem is very simple, only have to count the number of like terms, and write that number as a power.
(–5) • (–5) • a • a • a • (m + 3) • (m + 3)
(–5) • (–5) = 2 then: (–5)²
a • a • a = 3 a³
(m + 3) • (m + 3) = 2 (m + 3)²
Now, write the complete expresion
(–5)² • a³ • (m + 3)²
