If m is not equal to zero, and m+1/m = 1, then what is the value of m^4 + (1/m)^4?	Choose the correct choice
A) - 5	B) - 4	C) - 3	D) - 2	E) - 1

Rationale: m + 1 / m = 1 we square both sides so we have m ^ 2 + 1 / m ^ 2 + 2 = 1 or m ^ 2 + 1 / m ^ 2 = - 1 squaring again we have m ^ 4 + 1 / m ^ 4 + 2 = 1 or m ^ 4 + 1 / m ^ 4 = - 1 answer = - 1 ( e )
Answer: E
