Question

Solve the logarithmic equation.

 

4 log  x = -8

 

(round to the nearest thousandth as needed. Use a comma to seperate answers as needed)

Answer 1

Hi Keith;

4 log x=-8

Divide both sides by 4...

log x=-2

This is also...

log₁₀x=-2

We will move the 10 over.  It will be transformed from a base into a number...

x=10^-2

x=1/10²

x=1/100
