log 8x^3 = 4
8x^3 = 10^4 = 10000
x^3 = 1250
x = 10.77217
Solve the logarithmic equation. Round to the nearest ten-thousandth if necessary.

Thank you, but can you tell me what happened to the 8? Did you divide it by 10000?
No. I divided 10000 by 8
That is, I divided both sides of the equation by 8.
jeez
If you are working with logarithms, you surely must remember your Algebra I !

Maybe Nickie meant to type
log base 8 x^3 = 4
then
x^3 = 8^4
x^3 = (2^3)^4 = 2^12
x = 2^4 = 16
log base 8 x^3 = 4
then
x^3 = 8^4
x^3 = (2^3)^4 = 2^12
x = 2^4 = 16
log 194
