if log (x) = -0.123, what does x equal?

raise both sides to the power of e

e^(log(x))=e^(-0.123)
since e^(log(a)=a, so
x=e^(-0.123)

To find the value of x in the equation log(x) = -0.123, we can use the fact that logarithm functions are the inverse of exponentiation functions. In other words, if log(x) = y, then x = 10^y.

In this case, we have log(x) = -0.123. To find x, we need to raise 10 to the power of -0.123.

x = 10^(-0.123)

Approximately, x equals 0.744
