We'll write both bases as power of
2:
2^4(x-1)>2^(2x+2)
Since
the bases are bigger than unit value, the function is increasing and we'll
get:
4(x-1)> 2x+2
We'll
divide by 2:
2(x- 1) > x +
1
We'll remove the
brackets:
2x - 2 > x +
1
We'll subtract x both
sides:
2x - x - 2 > 1
x
- 2 > 1
We'll add 2 both
sides:
x > 2 + 1
x
> 3
The interval of values of x, for
the inequality holds, is (3 , +infinite).
