Method of health promotion
x + 1/x = 5
x^2 + 1/x^2 = ??
sqr both side
so answer is 23
The question gives you x+(1/x)=5 and it is asking for x^2+(1/x^2)
well, remember (a+b)^2=a^2+2ab+b^2
Let's square the question given, that gives you x^2+2*x*(1/x)+(1/x^2)=25
(Sqrt3)^5 * (9^2) = (3^x)*(3*Sqrt3)
If we know
x + 1/x =2
then what would be the value of
x^2048 + 1/x^2048 +x^2047 - 1 / x^2047 + 1/x^2049 - x^2049 +2
