Evaluate the expression (ab)2 for a = 4 and b = 3. A. 36 B. 24 C. 81 D.144

Answer:

Option D = 144

Step-by-step explanation:

First, you are not putting the expression correctly. I'm assuming you are mean to say (ab)². This is because if you want to multiply by 2, the 2 usually goes first like this 2ab. But it's not case, so, it should be as I said.

Now, let's replace the values for a and b into the expression:

(ab)² = (4 * 3)² = (12)² = (12*12) = 144

That's is why is option D.
