Practice Quiz or MCQ (Multiple Choice Questions) with solutions are av...
| 1 -i|^x = 2^x
we know,
|a + ib| = √(a² + b²) use this concept here,
so, |1 - i| = √{1² + (-1)²}
= √(1 + 1) = √2
now,
| 1 - i|^x = 2^x
(√2)^x = 2^x
(2½)^x = 2^x
2^(x/2) = 2^x
x/2 = x
x/2 - x = 0
x/2 = 0
x = 0
we know,
|a + ib| = √(a² + b²) use this concept here,
