- 10 \cdot 8^{- 5 n} = - 81

n = - \frac{ln ( \frac{81}{10} )}{15 ln ( 2 )}

Decimal Notation

n = - 0.20119 \dots

Solution steps

- 10 \cdot 8^{- 5 n} = - 81

Divide both sides by

- 10

8^{- 5 n} = \frac{81}{10}

Apply exponent rules

- 5 n ln (8) = ln (\frac{81}{10})

Solve

- 5 n ln (8) = ln (\frac{81}{10}) : n = - \frac{ln ( \frac{81}{10} )}{15 ln ( 2 )}

n = - \frac{ln ( \frac{81}{10} )}{15 ln ( 2 )}

8^{x - 1} = 4^{x + 1}

e^{\frac{x}{5}} = 12

2^{4 x - 1} = 128

0.5 = c e^{30 k}

3^{x - 1} + 2 \cdot 3^{x} = 63
