Answer:
Last option is correct
104x^4 + 16x^4√30
Step-by-step explanation:
let’s simplify what we have in the roots;
4x √(5x^2) = 4x^2 √5
(4x^2√5) + 2x^2 √(6)^2
(4x^2√5)(4x^2√5) + 4x^2√5(2x^2√6) + 2x^2√6(4x^2√5) + 2x^2√6(2x^2√6)
= (16 * x^4 * 5) + (8 * x^4 * √30) + (8 * x^4 * √30) + (4 * x^4 *6)
= 80x^4 + 8x^4 √30 + 8x^4 √30 + 24x^4
= 104x^4 + 16x^4√30
