Factor the following:
y = (x-a)^5 . (x-c)^5 . (a-c)^5
It looks already factored to me
You're right, the expression y = (x-a)^5 . (x-c)^5 . (a-c)^5 is already factored. Each term in the expression represents a factor, and by multiplying all the factors together, you obtain the original expression.
In general, a factored form expresses an expression as a product of multiple terms, and each term is typically written with parentheses around it. Here, you have three factors: (x-a)^5, (x-c)^5, and (a-c)^5, which are all raised to the power of 5.
If you wanted to expand the expression, you could distribute the exponents into each factor and simplify further. However, the given expression is already in its factored form, and there doesn't seem to be a need for further simplification.
