9^x=2

9^{x} = 2

x = \frac{ln ( 2 )}{2 ln ( 3 )}

Decimal Notation

x = 0.31546 \dots

Solution steps

9^{x} = 2

Apply exponent rules

x ln (9) = ln (2)

Solve

x ln (9) = ln (2) : x = \frac{ln ( 2 )}{2 ln ( 3 )}

x = \frac{ln ( 2 )}{2 ln ( 3 )}

10 e^{16 x} = 16

4 \cdot 3^{x} = 12 \cdot 5^{x}

e^{2 x} - 14 e^{x} + 13 = 0

3^{2 x - 1} - 8 \times 3^{x - 1} = 3

1 0^{4 x} = 72
