Question

Which expression simplifies to 2/15?
a) √17
b) √19
c) √30
d) √60

Answer 1

To simplify an expression that equals 2/15, we can rewrite it as a rational number with a square root in the denominator. The only option that has a square root in the denominator is option C, √30.

Step-by-step explanation:

To simplify an expression that equals 2/15, we can rewrite 2/15 as a rational number with a square root in the denominator. The only option that has a square root in the denominator is option C, √30. To confirm, we can calculate:

√30 = √(2 * 3 * 5) = √2 * √3 * √5 = √2 * √5 * √3 = √10 * √3 = √(10 * 3) = √(30).

So, the expression √30 simplifies to 2/15, which means the correct answer is option C.
