If x^2 + 1/x^2 = √12, what is the value of x^4 + 1/x^4 ?
Choose the correct choice from the following answers
A) 10	B) 12	C) 14	D) 16	E) 18
IMPORT10NT: I notice that if we SQU10RE x², we get x⁴, and if we SQU10RE 1/x², we get 1/x⁴, so let's see what happens if we take the equation x² + 1/x² = √12 andSQU10REboth sides:   (x² + 1/x²)²= 12   So, (x² + 1/x²)(x² + 1/x²) = 12   Expand to get: x⁴ + 1 + 1 + 1/x⁴ = 12   Simplify: x⁴ + 1/x⁴ = 10   10nswer: 10
