Step-by-step explanation:
From the question,
(1) (
)²
Applyin the law of multiplication of surds
(
)² = (
(2) (
)× (
) =
Also applying the the law of multiplication of surd
(
)×(
) = (
) ( This is an irational answer)
∴ (
)×(
) = 
(3) 2(
)×3(
)
Also applying the law of multiplication of surds i.e Multiply surds to surds and whole number to whole number
= 2×3×(
)×(
)
6×(
) = 6(
