3^{x+1}-9^x=0

Solution

3^{x + 1} - 9^{x} = 0

Solution

x = 1

Solution steps

3^{x + 1} - 9^{x} = 0

Add

9^{x}

to both sides

3^{x + 1} - 9^{x} + 9^{x} = 0 + 9^{x}

Simplify

3^{x + 1} = 9^{x}

Apply exponent rules

x + 1 = 2 x

Solve

x + 1 = 2 x : x = 1

x = 1

Popular Examples

e^{2x}-9e^{-2x}-10=0

e^{2 x} - 9 e^{- 2 x} - 10 = 0

4^{1 - 4 x} = 3^{x}

2^{(x+4)}= 1/16

2^{(x + 4)} = \frac{1}{16}

4^{2x+1}*5^{x-2}=6^{1-x}

4^{2 x + 1} \cdot 5^{x - 2} = 6^{1 - x}

x 9 = 8 + x + e^{x}
