+1

Decimal Notation

x = 0.66666 \dots

Solution steps

3^{x} = 9^{2 x - 1}

Apply exponent rules

x = 2 (2 x - 1)

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

x = \frac{2}{3}

Popular Examples

3^{7 x} = 3.3

\frac{1}{3} \cdot 2^{x} = 12

3^{x+1}-4+1/(3^x)=0

3^{x + 1} - 4 + \frac{1}{3 ^{x}} = 0

1 0^{x} = 22.4

2^{2x-1}=2^{2x}+2^{-1}

2^{2 x - 1} = 2^{2 x} + 2^{- 1}
