We can observe that the index of the radicals and the value inside are exactly the same, so we can immediately simplify the given radical expression.
2sqrt(6)
Practice makes perfect
We can observe that the index of the radicals and the value inside are exactly the same so we can immediately simplify the given radical expression. We will consider the properties for combining radical expressions when they are part of a sum or difference.
asqrt(x)+bsqrt(x)=(a+b)sqrt(x)
asqrt(x)-bsqrt(x)=(a-b)sqrt(x)
Let's use one of these properties to simplify our radicals.
