Answer:
The value of given expression (ab)² is 144.
Explanation:
Given information: a = 4 and b = 3
We need to find the value of expression (ab)² for the given values.
Since the value of a is 4 and the value of b is 3, therefore substitute a = 4 and b = 3 in the given expression.

On multiplication , we get

On simplification, we get

Therefore the value of expression (ab)² for a = 4 and b = 3 is 144.
