1. Solve the following equations
a) log(base 2) x+1 + log(base 2) x-1 = 3
(x+1)(x-1)=8
x^2-1=8
x^2=9
x=±3
..
b) log(base 2) x^2-1 =3
x^2-1=8
x^2=9
x=±3
..
c) explain why the equations log(base 2) x+1 + log(base 2) x-1 = 3 and log(base 2) x^2-1 =3 are not equal.
The equations of a) and b) are equal as shown above.
