Question #6bd15

Answer 1

Answer: `6sqrt(2)`

Explanation:

Evaluate: `3*sqrt(8)`
(Assuming question meant square root)

Note that `sqrt(a^2)=a`

We can only take out squares out of a square root, so we first write out the prime factorization of 8 inside the root:
`3*sqrt(2^3)`

We can see that there is one square, `2^2`, which we can take out:
`3*2*sqrt(2)`

Now, we can simplify:
`6sqrt(2)`

which is our final answer.
