What is the value of (8 + 3a) x a when a = 1/3

Substitute a for (1/3).

(8+3 (1/3)) * (2/3)

(8+1) * (2/3)

9 * (2/3)

6

The given equation is:

(8+3a) * a

To get the value at a=1/3, we will substitute the value of a in the given equation with 1/3 and compute the result as follows:

(8+3 (1/3)) * (1/3)

(8+1) * (1/3)

(9) * (1/3) = 3
