#### Answer

Yes, the expressions are equivalent.

#### Work Step by Step

We start by simplifying the first expression, $\frac{3}{4}\times d\times4$:
The commutative property of multiplication states that changing the order of the factors does not affect the product.
We use this property to rearrange the factors: $\frac{3}{4}\times4\times d$
Now, we simplify using the order of operations:
We multiply from left to right: $3\times d=3d$
Since this is equal to the second expression, the expressions are equivalent.
