*2√8
*12√2
*24√2
*24√8​

Answer 1

Answer:

12 root 2

Step-by-step explanation:

You can write 3 root 8 as 3× root of (4 ×2) = 3×2× root 2 = 6 root 2

Therefore

6 root 2 + 4 root 2 + 2 root 2 = 12 root 2

Answer 2

Answer:

12√2

Step-by-step explanation:

given,

3√8 + 4√2 + 2√2

we can write each as a multiple of √2,

3 x √4x2 + 4√2 + 2√2

since √4 = 2 so,

3 x 2√2 + 4√2 + 2√2

6√2 + 4√2 + 2√2

on adding these we get,

12√2
