SOLUTION: I need help to solve the logarithmic equation log10x=3. The 10 is lower in position, but I cannot type it that way. Then be sure to reject any value of x that is not in the domain

Question 1006525: I need help to solve the logarithmic equation log10x=3. The 10 is lower in position, but I cannot type it that way. Then be sure to reject any value of x that is not in the domain of the original logarithmic expression. Then give the exact answer.

Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
log 10 (x)=3
10^3=x; 10^log 10 (x)=x; 10^3=1000
x=1000
x cannot be less than or equal to zero, because anything raised to any power is >0. If one needs a negative number, a negative sign has to be placed in front of the whole expression.
