4^{x} + 9 \cdot 2^{x} + 23 = 0

No Solution for x \in R

Solution steps

4^{x} + 9 \cdot 2^{x} + 23 = 0

Apply exponent rules

(2^{x})^{2} + 9 \cdot 2^{x} + 23 = 0

Rewrite the equation with

2^{x} = u

(u)^{2} + 9 u + 23 = 0

Solve

u^{2} + 9 u + 23 = 0 :

No Solution for

u \in R

No Solution for x \in R

\frac{2 ^{x + 2}}{16} = 2

2^{3 x} = \frac{1}{8}

3 \cdot 2^{2 x} - 18 (2^{x}) + 24 = 0

5 \cdot 6^{- 4 x + 3} - 3 = 11

2^{x + 4} \cdot \frac{1}{8 ^{x}} = 1
