Option D: is the expression equivalent to
Explanation:
Option A:
The expression can be written as
Applying exponent rule, we get,
Thus, the expression is not equivalent to the expression
Hence, Option A is not the correct answer.
Option B:
The expression can be written as
Applying exponent rule, we get,
Thus, the expression is not equivalent to the expression
Hence, Option B is not the correct answer.
Option C:
The expression can be written as
Applying exponent rule, we get,
Thus, the expression is not equivalent to the expression
Hence, Option C is not the correct answer.
Option D:
The expression can be written as

Thus, the expression is equivalent to the expression
Hence, Option D is the correct answer.
Answer:
Step-by-step explanation:
For this case we have the following value:
We can convert this first to like this:
Now we use the fact the the pressure is defined as , whre P is the pressure, F the force and A the area, so then
and then we can replace this:
Now from definition of work we know that where W is the work, F the force and d the distance, so then is equivalent
And if we replace this into the equation we got:
