You can
put this solution on YOUR website!Express answer as decimal rounded to 3 decimal places. (1/4)x=5(1-x) x is exponent for 1/4 and 1-x is exponent for the 5.
:
:
Find the log of both sides
Use the log equivalent of exponents:
Find the logs:
-.60206x = .69897(1-x)
:
-.60206x = .69897 - .69897x
:
+.69897x - .60206x = .69897
:
.09691x = .69897
x =
x = 7.212568 Rounded to 7.213

Check on your calc:
enter .25^7.213 = 4.543(10^-5)
and
5^-.6.213 = 4.543(10^-5) close enough to confirm our solution
