Question

Help plz help needed i need the answer

Answer 1

The third option

Explanation:

If we rewrite this in log form, we get

`e {}^(0) = {x}^(2) - 25`

Remeber anything to the 0 power is 1, so simplifying the equation first

`1 = {x}^(2) - 25`

Add 25 to both sides

`26 = {x}^(2)`

Take the square root of both sides

`x = √(26)`

Square root are both so

`x = - √(26)`

Is also a answer.

The third option is the answer

Answer 2

x = ±sqrt(26)

Explanation:

ln ( x^2 -25) = 0

Raise each side to base e

e^ln ( x^2 -25) = e^0

x^2 -25 = 1

Add 25 to each side

x^2 -25 +25 = 1+25

x^2 = 26

Take the square root of each side

sqrt(x^2) = ±sqrt(26)

x = ±sqrt(26)
