Write the expression using exponents.

(–5) • (–5) • a • a • a • (m + 3) • (m + 3)

The answer to your question is:         (–5)² • a³ • (m + 3)²

Step-by-step 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

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
