the domain:
the equation:
4 is in the domain
-2 is not in the domain
The answer:
***
Also, the answer in 13 is {8}. -3 is not in the domain. Replace x with -3 and you'll see:
It's not true so -3 isn't a solution to this equation.
Look at the steps used when solving 4(x−3) = 8

Yay, geometric sum
an=8(2)^(r-1)
anyway, sum of geometric sequence where a1=first term and n=which one and r=common ratio is
so
first term is 50
common ratio is 2
n=8
