Answer:
Expressions are not equivalent
Step-by-step explanation:
Given expressions are:
Putting w=1 in both expressions
Both expression have value 28 on w=1
Putting w=3 in both expressions
Both expression have different values at w=3
Hence, in order for the expressions to be equivalent they both should produce same value on w=3 too.
So, it can be concluded that both expressions are not equivalent ..
