Answer: On multiplying (ab) and (ab), the result will be (ab)2 or a2b2.
The steps to multiply (ab) and (ab) are: ab x ab = (ab)2. To understand it in a better way, let us assume the value of a = 2 and the value of b = 1. So, the number will be 21. Now we will do the multiplication of 21 x 21. On multiplying 21 with 21 the result will be 21 x 21 = (21)2 or 441. Here it is clearly visible that on multiplying 21 with 21, the result is a square of 21. Similarly, when ab will be multiplied by ab, the answer will be (ab)2.
Summary:
Multiply ab and ab
On multiplying ab and ab, the result will be square of ab i.e. (ab)2 or a2b2.
