Answer 2

To evaluate the expression (3-b)(3+b)(9+b^2)+(8+b^2)^2 when b = 1/4, we substitute the value of b into the expression and perform the calculations.

Let's calculate step by step:

(3-b) = (3 - 1/4) = 11/4 (3+b) = (3 + 1/4) = 13/4 (9+b^2) = (9 + (1/4)^2) = 9 + 1/16 = 145/16 (8+b^2) = (8 + (1/4)^2) = 8 + 1/16 = 129/16

Now, let's substitute the values back into the expression and simplify:

(11/4)(13/4)(145/16) + (129/16)^2

= (11/4)(13/4)(145/16) + (129/16)^2

= (1113145 + (129)^2) / (4416)

= (2015 + 16641) / 256

= 18656 / 256

= 73

Therefore, when b = 1/4, the value of the expression (3-b)(3+b)(9+b^2)+(8+b^2)^2 is 73.
