Order the steps to solve the equation log3(x 2) = log3(2x2 − 1) from 1 to 6. 0 = (2x − 3)(x 1) 0 = 2x2 − x −3 Potential solutions are −1 and 3 2. 2x − 3 = 0 or x 1 = 0 x 2 = 2x2 − 1 3log3(x 2) = 3log3(2x2 − 1).

Respuesta :

The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number.

Ordered steps to solve the equation are,

  • 1)   [tex]3^{\log_3(x^2) }=3^{\log_3(2x^2 - 1)}[/tex]
  • 2) [tex]0=2x^2-x-3[/tex]
  • 3) [tex]0=2x^2-x-3[/tex]
  • 4) [tex](2x-3)(x+1)=0[/tex]
  • 5)  [tex]2x-3=0,\;\;\;\;x+1=0[/tex]
  • 6) The potential solution are -1 and 3/2.

What is exponent of log rule?

The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number.

For example,

Let k is the number and a is the base thus,

[tex]a^{log_a(k)}=k[/tex]

Given information-

The equation given in the problem is,

[tex]\log_3(x^2) =\log_3(2x^2 - 1)[/tex]

Order of steps to solve the equation are-

  • 1) Take the base 3 both the sides as,

         [tex]3^{\log_3(x^2) }=3^{\log_3(2x^2 - 1)}[/tex]

  • 2)The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number. Thus,

          [tex]x^2+2=2x^2-1\\[/tex]

  • 3) Take the variable with same power one side and solve them by equating to zero, we get,

           [tex]0=2x^2-x-3[/tex]

  • 4)Use the split the middle term method to make the group as,

          [tex](2x-3)(x+1)=0[/tex]

  • 5) Equate the factors to the zero as,

            [tex]2x-3=0\\x+1=0[/tex]

  • 6) Solve the above factors as, we get the potential solution are -1 and 3/2.

Hence, ordered steps to solve the equation are,

  • 1)   [tex]3^{\log_3(x^2) }=3^{\log_3(2x^2 - 1)}[/tex]
  • 2) [tex]0=2x^2-x-3[/tex]
  • 3) [tex]0=2x^2-x-3[/tex]
  • 4) [tex](2x-3)(x+1)=0[/tex]
  • 5)  [tex]2x-3=0,\;\;\;\;x+1=0[/tex]
  • 6) The potential solution are -1 and 3/2.
