Question

expand (y- root 3)³
​

Answer 1

b )³ = a³ + b³ + 3ab ( a + b )

⇒ (100 + 2)³

⇒ (100)³ + (2)³ + 3 × 100 × 2 (100 + 2)

⇒ 1000000 + 8 + 600 ( 102 )

⇒ 1000000 + 8 + 61200

⇒ 1061208

Therefore the answer is 1061208

Answer 2

Answer:

$({y - \sqrt{3} )}^{3}$

${y}^{3}-3-3\times\:y\times \sqrt{3}(y - \sqrt{3} )$

${y}^{3} - 3 - 3 \sqrt{3} {(y)}^{2} + 9 y$

${y}^{3} - 3 \sqrt{3} {y}^{2} + 9y - 3$
