Question 573675
A person has 7 children including 2 sets of triplets. the product of the kids ages is 6591.
:
Let x = the single child
let y = the one set of triplets
Let z = the other set of triplets
:
In order to make this manageable, assume that one set of triplets is 1 yrs old. 
 :
{{{x*y^3*1^3}}} = 6591
{{{x*y^3}}} = 6591
{{{y^3}}} = {{{6591/x}}}
y = {{{3sqrt(6591/x)}}}, that's cube root
Only one integer solution to this equation (the table of y=, in a ti-83)
x = 3
y = 13
:
3 * 13^3 * 1^3 = 6591
"
"what is the sum of their ages?"
3 + 13 + 13 + 13 + 1 + 1 + 1 = 45
