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

x = \frac{ln ( \frac{25}{8} )}{ln ( 2 )}

Decimal Notation

x = 1.64385 \dots

Solution steps

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

Move

3

to the right side

2^{x} = \frac{25}{8}

Apply exponent rules

x ln (2) = ln (\frac{25}{8})

Solve

x ln (2) = ln (\frac{25}{8}) : x = \frac{ln ( \frac{25}{8} )}{ln ( 2 )}

x = \frac{ln ( \frac{25}{8} )}{ln ( 2 )}

4^{x + 2} = 4^{5}

(e)^{z} = - 2

2^{2 x + 5} 0. 6^{x} = 1 2^{x}

9^{x - 2} = 2 7^{x}

x^{4 x} = 2
