4^{x+3}-4^{x+2}=24

4^{x + 3} - 4^{x + 2} = 24

x = - \frac{1}{2}

Decimal Notation

x = - 0.5

Solution steps

4^{x + 3} - 4^{x + 2} = 24

Factor

4^{x + 3} - 4^{x + 2} : 3 \cdot 4^{x + 2}

3 \cdot 4^{x + 2} = 24

Divide both sides by

3

4^{x + 2} = 8

Apply exponent rules

2 (x + 2) = 3

Solve

2 (x + 2) = 3 : x = - \frac{1}{2}

x = - \frac{1}{2}

e^{3 x} = 2

2 = e^{x}

9^{2 x - 5} = 27

2 e^{3 x} - 3 = 15

8^{x - 1} = 6^{3 x}
