Step-by-step explanation:
We can write sq root (- 18) as = sq root [3 x 3 x (-2)]
Similarly sq root ( - 8) = sq root [2 x 2 x (-2)]
2 sq root [2 x 2 x (-2)] - 3 sq root [3 x 3 x(-2)]
We simply,
2 x2 sq root (-2) - 3 x 3 sq root (-3)
4 sq root (-2) - 9 sq root (-2)
Bcoz sq root (-2) is common in bot term so
So
Sq root (-2) (4-9)
-5 sq root (-2) answer
