Question

x=1-√2. find( x-2/3)^3​

Answer 1

Answer:

{(X - 2)/ 3}³

{(1 - √2 -2 )/3}³

{( -1 - √2)/3)}³

( -1 - √2)³/ 3³ { (a + b)³ = a³ + b³ + 3a²b + 3 ab²}

{(-1)³ + (-√2)³ + 3(-1)(-√2)² + 3(-1)²(-√2)} / 27

{ -1 - (√2)^7/2 - 6 - 3√2}/27

( -7 - (√2)^7/2 - 3√2)/ 27

I mean behna, isse zaada simplify naa hora. aur na isse zaada simplify Ki zaroorat hogi school answer me.

Fir bhi plzzzz mark brainliest
