ANSWER:
[tex] {81}^{2} - 25[/tex]
--------------
Answer using formula (a-b) (a + b) =
[tex] {a}^{2} - {b}^{2} [/tex]
Simplify the product.
[tex] {(9m)}^{2} - {5}^{2} [/tex]
Then, evaluate the powers. To raise a product to a power, raise each factor to that power.
[tex] {9}^{2} {m}^{2} - {5}^{2} [/tex]
Final Answer:
[tex] {81m}^{2} - 25[/tex]
