Webbx = 1000 Explanation: We have: log10(x) = 3 Using the laws of logarithms: ⇒ x = 103 ⇒ x = 1000 ... Find the range of a logarithmic function whose domain is all real numbers between 2 and 10 (exclusive). 2 < x < 10 3 < x +1 < 11 log10 3 < log10(x+1) < log10 11. (The last step is due to the fact that log10 is an increasing function.) WebbEquation Solving Solve equations in one or more variables both symbolically and numerically.

Answer To subtract rational expressions, they must also have a common denominator. When the denominators are the same, you subtract the numerators and place the difference over the common denominator. Be careful of the signs when you subtract a binomial or trinomial.
