Question 962607

Solve the exponential equation algebraically. Approximate the result to three decimal places. (Enter your answers as a comma-separated list.)
4^(1 − x) = 315
<pre>{{{4^(1 - x) = 315}}} ------- Exponential form
{{{log (4, 315) = 1 - x}}} ----- Logarithmic form
{{{x = 1 - log (4, 315)}}}, or {{{- 3.1496}}}, or {{{highlight_green(- 3.150)}}}
