# Square root of 2(5 + square root of 8) is irrational and equal to what kayden1234thomp
We are given with two factors: square root of 2 and 5 + square root of 8. We use a scientific calculator that displays irrational answers. The product of the two factors is 4 + 5 square root of 2. The answer is irrational since the square root sign in the answer is present. snikergrace
Sqrt2(5+sqrt8) = 5sqrt2 +sqrt16 = 4+5sqrt2 so result that choice D. is right sure GiuliAzevedo
Hello,

√2*(5+√8)=5√2+4 DangerDash

Step-by-step explanation: jasmineunderwoo264

Step-by-step explanation:

In order to determine the group of numbers, we have to use the properties of root.

The number is: Then, we have to know three definitions:

All rational numbers can be written as fractions equation, with a being an integer and b being a natural number. Irrational numbers can not be written as fractions notation.When a prime number is inside of a square root, the number is always a irrational.

Finally, has a , that it is a irrational number, therefore the addition is a irrational number too. serafimharmane4944

For this case we have the following product: Applying the distributive property we have: Then, rewriting the expression we have:  We note that the answer is a irrational number, because the square root of two is not an exact number. It is irrational and equal to 4 + 5square root of 2. gbprulesmile
