Identify Equation Type: Step Title: Identify the Type of EquationConcise Step Description: Determine the type of equation we are dealing with to apply the appropriate method for solving it.Step Calculation: The equation is 132x−5⋅3x+6=0. This is not a standard quadratic equation due to the different bases of the exponents. However, we can try to transform it into a quadratic form by substitution if possible.
Find Substitution: Step Title: Look for a SubstitutionConcise Step Description: Find a substitution that can transform the equation into a quadratic form.Step Calculation: Let's denote 3x as 'y'. Then, 132x can be written as (3x)2, which is y2. The equation now looks like y2−5y+6=0, which is a quadratic equation in terms of 'y'.
Factor Quadratic Equation: Step Title: Factor the Quadratic EquationConcise Step Description: Factor the quadratic equation obtained after the substitution.Step Calculation: We need to find two numbers that multiply to 6 (the constant term) and add up to −5 (the coefficient of the 'y' term). The numbers that satisfy these conditions are −2 and −3. Therefore, the factored form is (y−2)(y−3)=0.
Solve for Substituted Variable: Step Title: Solve for the Substituted VariableConcise Step Description: Solve the factored equation for the substituted variable ' extit{y}'.Step Calculation: We have two possible solutions for ' extit{y}': y−2=0 or y−3=0. This gives us y=2 or y=3.
Back-Substitute for 'x': Step Title: Back-Substitute to Solve for 'x' Concise Step Description: Replace 'y' with 3x and solve for 'x'. Step Calculation: Since y=3x, we have two equations: 3x=2 and 3x=3. Solving for 'x' gives us x=log3(2) and x=log3(3). The second equation simplifies to x=1 because 31=3.
Solve Logarithmic Equations: Step Title: Solve the Logarithmic EquationsConcise Step Description: Solve the logarithmic equations to find the values of x.Step Calculation: The first equation is x=log3(2). This cannot be simplified further without a calculator. The second equation has already been simplified to x=1.
