When simplifying radicals, you want to factor the radicand and look for square numbers.
Both the and are not perfect squares, so the answer is just .
Example Question #11 : Simplifying Radicals
Simplify.
When simplifying radicals, you want to factor the radicand and look for square numbers.
is a perfect square so the answer is just .
Example Question #4003 : Algebra Ii
Simplify.
When simplifying radicals, you want to factor the radicand and look for square numbers.
If you aren't sure whether can be factored, use divisibility rules. Since it's odd and not ending in , lets check if is a possible factor. To know if a number is factorable by , you add the sum of the individual numbers in that number.
Since is divisible by , just divide by and continue doing this. You should do this more times and see that .
Since is a perfect square, or we can simplify the radical as follows.
Example Question #11 : Simplifying Radicals
Simplify.
When simplifying radicals, you want to factor the radicand and look for square numbers.
Since is a perfect square but is not, we can write it like this:
Remember, the other factor that's not a perfect square is left in the radicand and the square root of the perfect square is outside the radical.
Example Question #4005 : Algebra Ii
Simplify.
When simplifying radicals, you want to factor the radicand and look for square numbers.
Since is a perfect square but is not, we can write it as follows:
Remember, the other factor that's not a perfect square is left in the radicand and the square root of the perfect square is outside the radical.
Example Question #4006 : Algebra Ii
Simplify.
When simplifying radicals, you want to factor the radicand and look for square numbers.
Since is a perfect square but is not, we can write it like this:
Remember, the other factor that's not a perfect square is left in the radicand and the square root of the perfect square is outside the radical.
If you didn't know was a perfect square, there's a divisibility rule for . If the ones digit and hundreds digit adds up to the tens value, then it's divisibile by . so is divisible by and its other factor is also . It's best to memorize perfect squares up to
Example Question #11 : Simplifying Radicals
Simplify.
When simplifying radicals, you want to factor the radicand and look for square numbers.
It's essentially the same factor so the answer is .
Example Question #4011 : Algebra Ii
Simplify.
Let's see if this quadratic can be broken down. Remember, we need to find two terms that are factors of the c term that add up to the b term.
It turns out that .
The second power and square root cancel out leaving you with just .
Example Question #4012 : Algebra Ii
Simplify.
Let's factor a out first since they divide evenly with all of the terms.
We get
Let's see if this quadratic can be broken down. Remember, we need to find two terms that are factors of the c term that add up to the b term.
It turns out that .
We have perfect squares so the final answer is .
