Question

logx8=-0.5

Answer 1

\[x=1/\sqrt[16]{e}\]

Answer 2

In step sequence:
First rewrite the logarithm in index form: x^(-0.5)=8
We want the value of x, so raise both sides of the equals sign by power (-2):
x^((-0.5)(-2))=8^(-2)
This simplifies into: x=1/64

Answer 3

ok thanks so it can be 1/64 or -64 rite

Answer 4

I doubt that. To be sure, try plugging it into the index form: (-64)^(-0.5)=8
Got your answer? :)
