Answer:
I think its 57
Step-by-step explanation:
the difference of 6 divided by 2 is 3
i just divided 171 by 3 and got 57
(5/8):(1/4)= 5/8 • 4= 20/8=5/2 = 2 and 1/2
To simplify this expression, you have to remember that when
a number or a variable is raised to the negative exponent you have to
reciprocate the number. In this expression, c^-8 will be reciprocated so it
will become part of the numerator. Therefore, the final answer would be
12c^8/d^2.
