Question

5√27-4√48м-2√12м-15√3

Answer 1

√25•27=675
√16•48=768
√4•12=48
√225•3=675
675-768-48-675=-816

Answer 2

To simplify the expression, let's first simplify each square root term:

1. √27 can be simplified as √(3^3) = 3√3.
2. √48 can be simplified as √(4 * 12) = 4√12.
3. √12 can be simplified as √(4 * 3) = 2√3.

Now, the expression becomes:

5√3 - 4√12m - 2√3m - 15√3.

Next, let's combine like terms:

Since we have two terms with √3, we can combine them:

(5 - 2)m√3 - 4√12m - 15√3.

Simplifying further:

(3m - 4)m√3 - 4√12m - 15√3.

Lastly, we can't simplify √12 any further, so the final simplified expression is:

(3m - 4)m√3 - 4√12m - 15√3.
