Answer: C, b^-3.

Step-by-step explanation: If you multiply b*b*b you get b^3. Since b^3 is the denominator and the numerator is 1, you can just multiply the top and bottom by b^-3 to get rid of the denominator. b^3*b^-3 is 1, which effectively removes the denominator, and 1*b^-3 is b^-3. Thus, the answer is b^-3.

Answer:

C.

Explanation:

Multiplying identical variables together is identical to adding the exponents of each.

In this case, you have three
b^(1)s. You can multiply these to create
b^3.

Now, you have
(1)/(b^3).

Negative exponents mean that the base (b in this scenario) is on the opposite side of the fraction line.


(1)/(b^3) = b^(-3)
