1 0^{- x} = 4

x = - \frac{2 ln ( 2 )}{ln ( 10 )}

Solution steps

1 0^{- x} = 4

Apply exponent rules

- x ln (10) = ln (4)

Solve

- x ln (10) = ln (4) : x = - \frac{2 ln ( 2 )}{ln ( 10 )}

x = - \frac{2 ln ( 2 )}{ln ( 10 )}

5^{2 x - 3} = 1

2^{x} = 1 0^{13}

1 0^{3 x} = \frac{1}{10000}

9 = 3^{x}

9^{n + 10} + 3 = 81
