Which statement is true about the product square root of 2(3square root of 2 + square root of 14)?


It is rational and equal to 12.


It is rational and equal to 18.


It is irrational and equal to 6 + 2square root of 18.


It is irrational and equal to 3 +square root of 18.

Verified Answer :

Answer:

\(\sqrt{2} (3\sqrt{2} +\sqrt{14})=6+2\sqrt{7}\)

Step-by-step explanation:

Given : \(\sqrt{2} (3\sqrt{2} +\sqrt{14})\)

Solution:

\(\sqrt{2} (3\sqrt{2} +\sqrt{14})\)

\(3*2+\sqrt{28})\)

\(6+2\sqrt{7}\)

Thus ,  \(\sqrt{2} (3\sqrt{2} +\sqrt{14})=6+2\sqrt{7}\)

Thus the solution is irrational since square root 7 does not have a perfect square and equal to 6+2square root of 14
