प्रश्न

z1 = 1 + i, z2 = 2 − 3i. Verify the following : 

`bar("z"_1 - "z"_2) = bar("z"_1) - bar("z"_2)`

बेरीज

उत्तर

z1 = 1 + i, z2 = 2 − 3i

∴ `bar("z"_1)` = 1 − i, `bar("z"_2)` = 2 + 3i

z1 − z2 = (1 + i) − (2 − 3i)

= 1 + i − 2 + 3i

= − 1 + 4i

∴ `bar("z"_1 - "z"_2)` = − 1 − 4i 

`bar("z"_1) - bar("z"_2)` = (1 − i) − (2 + 3i)

= 1 − i − 2 − 3i

= − 1 − 4i 

∴ `bar("z"_1 - "z"_2) = bar("z"_1) - bar("z"_2)`
