a^4 - 81 is the product of the given identity.

Step-by-step explanation:

Given:

Find the product using suitable identity. (a+3) (a-3) (a^2 +9)

Solution:

Consider (a + 3) (a – 3)

By formula, (a + b) (a – b) = a^2 - b^2

(a + 3) (a – 3) = a^2 - 3^2

= a^2 - 9

(a+3) (a-3) (a^2+9) = (a^2 - 9) (a^2+9)

Applying the formula to the above expression,  

(a^2)^2 - 9^2 = a^4 - 81
