Answer:
4√3
Explanation:
To solve this we need to simplify √300 and 2√27
We know that √300=10√3, because 300=100×3, and the square root of 100 is 10.
We also know that 2√27=6√3 because 27=9×3, and the square root of 9 is 3. Multiply 3 by 2 and you get 6.
Since we cannot get a perfect square of 3 we just rewrite them.
So, √300-2√27=10√3-6√3=4√3
Hope this helps!
