To simplify the given radical expression, use a property for combining radical expressions when they are part of a sum.
8sqrt(5)
Practice makes perfect
To simplify the given radical expression, we can use a property for combining radical expressions when they are part of a sum.
asqrt(x)+bsqrt(x)=(a+b)sqrt(x)
Notice that radicals can only be added when the index and the value inside are exactly the same.
