Which do you think would be it?

OpenStudy (anonymous):

Remember the rules for fractions and exponents. Exponents mean that the number below is multiplied by themselves a certain number of times indicated by the exponent and when multiplying fractions it is similar to multiplying number except there are 2 numbers 1 on top and 1 on bottom.

A & D.. but I'm not too sure for this one..

OpenStudy (anonymous):

No, then that means 'A' is correct

OpenStudy (anonymous):

Let me show you why A is correct and maybe you can find the incorrect one that way: \[(\frac{ abc }{ 2 })^2= \frac{ abc }{ 2 } \times \frac{ abc }{ 2} = \frac{ (a^2b^2c^2) }{ 4 }\]

-See that's where I was confused, I didn't know you multiplied the denominator by the exponent-thanks . I just checked and both C and D are correct as well; therefore, B is the answer..

OpenStudy (anonymous):

Correct! Great job
