Answer 2

• (√17 + √2)/(√17 + √2)

Explanation:

You need to determine the conjugate of the denominator.

√17 - √2 has conjugate of √17 + √2, when multiplied the product is going to be a rational number:

• (√17 - √2)/(√17 + √2) = 17 - 2 = 15

Therefore correct choice is B or second from the top:

• (√17 + √2)/(√17 + √2)
