Answer:
The first answer choice is the correct one.
Step-by-step explanation:
√(120x) can be rewritten as √(4*30*x). I have chosen these factors because 4 is a perfect square. This √(4*30*x) can be simplified further, leading to
√4 * √(30x), which in turn equals 2√(30x),
The correct answer is the first one of the four given.
40 lol because 41 is the closest to 40
Answer:
6:60 or 1:10 if it must be simplified

Answer:
Step-by-step explanation:

21 has no 2 in it's prime factorization. So it can never end in 0, 2 , 4 , 6 , 8.
OR
Odd number raise to any number is always odd, Which does not include 2, 4, 6 , 8.
So
does not end with 0, 2, 4 , 6 , 8.
