If we have p^2+p^3 how can it be simplified ?

Please check my answer: Multiply and simplify (8a^7)/(11p^3) * (121p^8)/(64a) I got (968a^7p^8)/(704ap^3) Is this correct?

I came up with no solution for this equation. Could someone please let me know if I am correct? If not, I will try again, but I have already tried it 3 times. [x/(x+5)]-[5/(x-5)]=(x^2+25)/(x^2-25)

Add. Simplify, if possible. 4d/(5d-10) + 2d/(10d-20) I am simply having a difficult time with this one. Could you please just get me started? Thank you in advance!

I'm not sure how represent radicals, but here is the problem: -(sq root)-76 + (sq root)-125 It is my understanding that negative numbers do not have real-number square roots, so does that mean that this whole expression does not exist as a real number or...

Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on Earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: w=Cr^-2 ,...

Could someone please check my work on these word problems? My solutions just don't seem right, could you please let me know where I may have messed up. Many people know that the weight of an object varies on different planets, but did you know that the we...

Or, should I leave it as 10d/(10d-20), or do I factor out both of the 10d's to come up with -1/20? Please help me?

Ok.. So, would it be 11/8a^6p^5?

Ok, I gave it one more shot. PLEASE let me know if the answer is correct? 10d/[10(d-2)]

Ok, I went back and tried again. The equation I found when solving for r is r=sqrt(C/w) Is this correct? Then in b I would plug in the 100 for w, and the 3,963 for r to find the constant, C, correct?

So would my equation be C=100/(3963)^2 ...I'm confused

Please let me know if I did this correct for b... 100=C/(3,963)^2 100=C/15,705,369 100*C=(C/15,705,369)*C 100C=15,705,369 100C/100=15,705,369/100 C=157,053.69

"Hint: Pay attention to the units of measure. You may have to convert from feet to miles several times in this assignment. You can use 1 mile = 5,280 feet for your conversions."
