Solve the equation. log2 116 2x−5
WebSolve log2(8) = x. I can solve this by converting the logarithmic statement into its equivalent exponential form, using The Relationship: log 2 (8) = x. 2 x = 8. But 8 = 23, so I can equate powers of two: 2 x = 2 3. x = 3. Note that this could also have been solved by working directly from the definition of a logarithm. WebBest Answer. 100% (1 rating) x = ….

Dec 8, 2014 To check whether x = 3 is a solution to 2x - 5 < 7, you substitute 3 in for x and simplify the solution. If the statement is true then it is a solution.
WebCompleting the square method is a technique for find the solutions of a quadratic equation of the form ax^2 + bx + c = 0. This method involves completing the square of the quadratic expression to the form (x + d)^2 = e, where d and e are constants. WebExample 10.20. Find the value of x: ⓐ logx36 = 2, ⓑ log4x = 3, and ⓒ log1 21 8 = x. log x 36 = 2. Convert to exponential form. x 2 = 36. Solve the quadratic. x = 6, x = −6. The base of a logarithmic function must be positive, so we eliminate x = −6. x = 6 Therefore, log 6 36 = 2.
