Option (b) is the correct answer as the expression
.
Let's break down each expression to determine their equivalence:
a.
Expanding the left side:
The right side does not match, so option (a) is not equivalent.
b.
This matches the expanded left side of option (b), so option (b) is equivalent.
c.
This does not match the expanded left side of option (c), so option (c) is not equivalent.
d.
Expanding the left side:
This matches the expanded left side of option (d), so option (d) is equivalent.
In summary, the equivalent pair is option (b).
The question probable maybe:
Which pair shows equivalent expressions?
a.
b.
c.
d.
