Solve for x equation 1+log3 x =2 . Solution The solution of the equation has to respect the constraint of existence of logarithm: x > 0 We\'ll write the value 1 = log3 3 We\'ll use the produt rule of logarithms: log3 3 + log3 x = log3 (3x) We\'ll solve the equation, taking anti-log: log3 (3x) = 2 3x = 3^2 3x = 9 We\'ll divide by 3: x = 3 Since the value of x is positive, we\'ll accept it as solution of the equation, so x = 3..
