The correct answer is choice C
Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).
We split up the radicand into perfect squares. Once we do, we take out the things that were squared:

So let’s imagine this on a number line…so we know that the fish starts at -17 1/3 on the number line but he dives (that means go lower in our number line) 6 1/2 feet downward so let’s set up an equation:
-17 1/3 - 6 1/2
Now, let’s subtract the two integers by finding the least common denominator of 2 and 3 so it can be easier to solve in this case it’s 6…then let’s set up our new equation:
-17 2/6 - 6 3/6
We know it’s a negative number since we are subtracting a negative number and our final answer is -23 5/6
Answer:
26h
Step-by-step explanation:
-3(2h-10h)+2h
-6h+30h+2h=26h
X=64 how you not know that?
