Determine whether the statement is true, false, or sometimes true.
1) If x and y are both integers, 1)
then (x)3 = x3
A) Sometimes true B) True C) False

Reiny,
If you mean
(x)^{3 = x3 yes, that is always true As a matter of fact, it is true for all odd exponents of n for (x)n = xn and false for all even numbers of n. e.g. (3)^3 = (3)(3)(3) = 27 3^3 = (3)^3 = (3)(3)(3) = 27 but (3)^4 = (3)(3)(3)(3) = +81 and 3^4 = (3)(3)(3)(3) = 81}

Reiny,
Let's try that again
If you mean
(x)^{3} = x^{3}
yes, that is always true
As a matter of fact, it is true for all odd exponents of n for
(x)n = xn
and false for all even numbers of n.
e.g. (3)^3 = (3)(3)(3) = 27
3^3 = (3)^3 = (3)(3)(3) = 27
but
(3)^4 = (3)(3)(3)(3) = +81
and 3^4 = (3)(3)(3)(3) = 81
