All in parentheses, 3m^1/6 n^1/3 over 4n^-2/3 all to ^2. I'm having trouble simplifing the problem. If someone could explain on how to do it, it would help me out a lot. I'm studying for a test and it's been awhile since we've done this in class, so I don't remember how to do it. Thanks in advance...

I solved a problem and am wondering if its right. Basically, a person has 150 feet of fence to put around a rectangular garden. A 10-foot opening is left on one side for a gate. I have to determine the length and width for the maximum area. Since one side has an opening of 10, the side parallel to it is also going to be 10. 150-10= 140, which I divided by 2. So the other two sides are each 70, making the maximum area 700 cm^2. Is this right?

It should have a buzzer go off at a time dependent on the temperature of a liquid. The temperature-time relation is linear. It also has to have few components (not 20 op-amps).

Do black holes really exist seeing that black holes contradict the law that "energy cannot be created or destroyed, only transfered" when matter reaches an event horizon.
Are they any other theories like Dark Energy Stars that could explain it?
