Answer: third option 6∛5
Explanation:
24 = 2^3 * 3
45 = 3^2 * 5
=> 24 * 45 = 2^3 * 3^3 * 5
=> (∛24).(∛45) = ∛[ (2^3).(3^3).5 ] = (2)(3)∛5 = 6∛5

Answer: the third option: 7x^2 - 12x√14 + 72
Solution:
Notice that it is the two factors are identical, so this is a perfect square binomial:
(x√7 - 3√8)^2 = (x√7)^2 - 2*(x√7)(3√8) + (3√8)^2 = 7x^2 - 6√(56)x + 72 =
= 7x^2 -(6)(2)x√14 + 72 = 7x^2 - 12x√14 + 72
