Using remainder theorem, we get:
Substitute t = 5 into the equation:
Thus, we get a remainder of 93 or (A)
Substitute t = 5 into the equation:
Thus, we get a remainder of 93 or (A)
Answer:
Step-by-step explanation:
Let's rewrite the left side keeping in mind the next propierties:
Therefore:
Now, cancel logarithms by taking exp of both sides:
Multiply both sides by and using distributive propierty:
Substract from both sides and factoring:
Multiply both sides by -1:
Split into two equations:
Solving for
Add 4 to both sides:
Solving for
Collect in terms of x and add to both sides:
Divide both sides by e-2:
The solutions are:
If we evaluate x=4 in the original equation:
This is an absurd because log (x) is undefined for
If we evaluate in the original equation:
Which is correct, therefore the solution is:
