Given that a=2 and b=3, what is (ab)^2

(ab)² is the same as writing:

(a x b)²

We know that a is 2 and that b is 3, so we substitute these into the expression:

(2 x 3)²

Then because of the Order of Operations we multiply INSIDE the brackets first:

(6)²

And when we square (²) a number we are simply multiplying it by itself:

(6)² = 6 x 6

So our final answer is:

6 x 6 = 36
