@HelloGoodmorning

OpenStudy (anonymous):

Yes that is the expression ^^^ i'll post the options

Directrix (directrix):

Okay.

OpenStudy (anonymous):

\[\sqrt{14h^3}\]

OpenStudy (anonymous):

\[\sqrt{49h^3}\]

OpenStudy (anonymous):

Directrix (directrix):

I guess we'll need to check the options. I see a "3" as part of the radicand (expression under the radical symbol) of the given problem. ---> So, pick an option that has 3 as a factor of its radicand and we will test that one first. Tell me which one you picked, and we'll see how it simplifies.

OpenStudy (anonymous):

Okay I'm going to pick the second choice @Directrix

Directrix (directrix):

I should have been more specific. Look for an option that has an integer that is divisible by 3. In this option, 49 is not divisible by 3. The 3 exponent of h^3 "sorta" is but on the next option to test, pick one that has a "regular" integer that three divides. I have worked out the second option so that you can see how it breaks apart. So, choose another option to test, okay? |dw:1387172031030:dw|
