We are given the following function:


p(x)=3x^2-4

We are asked to determine the value of p(8a). That means that we will substitute the value of "x = 8a" in the function, like this:


p(8a)=3(8a)^2-4

Now, we solve the exponents using the following property:


(ab)^x=a^xb^x

Applying the property we get:


p(8a)=3(8^2a^2)-4

Solving the products we get:


p(8a)=192a^2-4

Since we can't simplify any further this is the final answer.
