If ⁻¹ x+ ⁻¹ y+ ⁻¹ z=3 , then the value of x²⁰²⁵+x²⁰²⁶+x²⁰²⁷ is
Options
- A-1
- B0
- C1
- D3
Correct answer
A. -1
Step-by-step solution
aligned & ⁻¹ x+ ⁻¹ y+ ⁻¹ z=3 & Since 0 ⁻¹ x & & 0 ⁻¹ y and 0 ⁻¹ z & & Here, ⁻¹ x= ⁻¹ y= ⁻¹ z= & x=y=z= =-1 & x²⁰⁰⁵+x²⁰²⁶+x²⁰²⁷ & =(-1)²⁰²⁵+(-1)²⁰²⁶+(-1)²⁰²⁷ & =-1+1-1 & =-1 aligned
