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.
Multiply ab and ab
On multiplying ab and ab, the result will be square of ab i.e. (ab)2 or a2b2.
