Step 2
Use the One-to-One Property to solve the equation for x.
logo(x- 9) logo(6)
Step 1
Identify the One-to-One Property.
a = x and aloga x = x.
loga
1 = 0 because a° = 1.
loga
If log, x = loga y, then x = y.
loga a = 1 because a = a.
Step 2
Apply the One-to-One Property to the equation.
log, (6)
X = 6
