A quant question (more)
QID : 61 - If x + (1/x) = 2, then what is the value of x64 + x121?
Options:
1) 0
2) 1
3) 2
4) – 2
Answer is Option 1) 0
But How?
x+(1/x)=2 x^2-2x+1=0 (x-1)(x-1)=0 x=1 X=1; therefore 1*64 + 1*121 =64+121=185 or Iâ€™m not sure what the question means. In the expression x64 + x121, are the numbers supposed to be exponents? If so, we could evaluate easily: 1^64 + 1^121 = 1+1 = 2.
