Example Questions
Example Question #11 : Exponents And Logarithms
Solve for 
can be rewritten as
Applying the Power of a Power Rule,
Example Question #22 : Mathematical Relationships
Solve the equation:
Rewrite the base of the right side.
Simplify the right side.
Add 6 on both sides.
Divide by 6 on both sides.
The answer is:
Example Question #23 : Mathematical Relationships
Solve:
Change the base of the left side to base two.
The equation becomes:
Set the exponents equal since they have similar bases.
Divide by 2 on both sides.
The answer is:
Example Question #51 : Sat Subject Test In Math Ii
Simplify:
Start by distributing the exponent in both the numerator and the denominator. Recall that when an exponent is raised to the exponent, you will need to multiply the two numbers together.
Next, recall that when you have numbers with different exponents, but the same base, subtract the exponent found in the denominator from the exponent in the numerator.
Recall that you can flip the fraction to make the exponents positive.
Example Question #52 : Sat Subject Test In Math Ii
Solve 
The first thing we need to do is find a common base. This can be tricky to do, but guessing and checking a little shows that:
Plugging that back in to the original equation:
Now that our bases are the same, we can cancel them:
From here, it's much easier to solve using simple algebra:
Example Question #53 : Sat Subject Test In Math Ii
Solve 
First, we gather all the constants on one side of the equation:
Next, we rewrite the equation in exponential form:
Now we can simplify the exponent:
And finally, divide:
Example Question #54 : Sat Subject Test In Math Ii
Solve 
Start by combining log terms. Remember, if you subtract logs, you divide the terms inside them:
Now we can rewrite the equation in exponential form:
Finally, we need to get the variable in the numerator, and then alone:
Example Question #55 : Sat Subject Test In Math Ii
Solve 
First, we combine log terms by subtracting them. Remember, when you subtract logs, you divide the terms inside them:
Now, because the bases of the logs match on either side of the equation, we can cancel them out:
From here, we use simple algebra to solve:
Example Question #21 : Exponents And Logarithms
Solve
First, subtract the natural log terms:
Now rewrite the equation in exponential form:
Finally, isolate the variable:
Example Question #21 : Mathematical Relationships
Solve
We can start by canceling the logs, because they both have the same base:
Now we can collect constants on one side of the equation, and variables on the other:
