klemol [59]

Answer:

Equivalent $3\sqrt{8}=6\sqrt{2}$

Step-by-step explanation:

Given: 3 radical 8

Mathematically 3 radical 8 can be written as $3\sqrt{8}$

We have to find an equivalent to $3\sqrt{8}$ .

Given expression can be written as ,

$3\sqrt{8}=3\sqrt{4 \times 2}$

On further simplification, we get,

$3\sqrt{4 \times 2}=3(\sqrt{4} \sqrt{2} )$

We know $\sqrt{4}=2$

further simplification gives,

$3\sqrt{8}=6\sqrt{2}$

Thus, Equivalent $3\sqrt{8}=6\sqrt{2}$
