how many balls are there?

I assume A B C D and E are all people?

Suppose that  x and y are positive integers such that  (x^2)(y^3)= 46656. What is the sum of all possible values of x?

factor(46656) = 2^6*3^6

\(2^6*3^6\\~\\ (2^3)^2* (3^2)^3=8^2*9^3\\ (3^3)^2*(2^2)^3 =27^2*4^3 \\1^2*(6^2)^3=1^2*36^3 \\(6^3)^2*1^3=216^2*1^3\)

Just as guest already determined.

I am not answering any more.

There is a policy of one question per post.

PLUS

We are not here to do all your homework for you.

In Zucchini squash a gene for white color (W) is dominant over its allele for yellow color (w). Give the genotypic and phenotypic ratios for the results of each of the following crosses: a. WW x ww b. Ww x ww c. Ww x Ww

T"Genotype" is an organism's full hereditary information.

"Phenotype" is an organism's actual observed properties

For a)    All of the plants will be   Ww     Genotype and

                  all will have the phenotype white 

For b)     Genotypes,  25% WW,    25% ww    and  50%    Ww

               Phenotypes    75% will be white and  25% will be yellow.

Have you drawn the pic?

Once you draw the pic you can just use Pythagoras's theorem to solve it.

No one else answer over me, thanks.

 The diagonal of the square is     \(\sqrt{2R^2}\)

You need to check my working for stupid errors.

Hint:

Use the difference of two squares         3 times.

Please no one expand on this.

If it says 31/9 is wrong, then try entering it in a different way.

I do not like any of those answers.

b  is absolutely incorrect.

d  perhaps not really related

a , well not really, but if you are talking very near future then I guess that is correct.  

c, the slope of a lined is always an integer.

So I guess we are left with only one possibility.

watch this.
