Question

Solve four square root of six plus eight square root of four and explain whether the answer is rational or irrational.

Answer 1

Answer:

$4\sqrt{6}+16$

Step-by-step explanation:

Given the expression: $4\sqrt{6}+8\sqrt{4}$

$\sqrt{4}=2\\ Therefore, \\4\sqrt{6}+8\sqrt{4} =4\sqrt{6}+8*2\\ =16+4\sqrt{6}$

We can re-write the answer as:

$4\sqrt{6}+16$

The answer is irrational because the sum of a rational number and irrational number is an irrational number.

The correct option is B.
