Question

if z1 =4-5i and z2=3+7i then find z1-z2​

Answer 1

$\Huge\bold{\boxed{Answer}}$

Z1 - Z2

= (4-5i)-(3+7i)

= 4-5i -3 -7i

= 1 -12i

$\colorbox{green}{Answer\:1 -12i }$

Answer 2

If z₁ = 4 - 5i and z₂ = 3 + 7i then z₁ - z₂ = 1 - 12i

Given :

z₁ = 4 - 5i and z₂ = 3 + 7i

To find :

The value of z₁ - z₂

Solution :

Step 1 of 2 :

Write down the given complex numbers

Here the given complex numbers are

z₁ = 4 - 5i and z₂ = 3 + 7i

Step 2 of 2 :

Find the value of z₁ - z₂

z₁ - z₂

$\displaystyle \sf{ = (4 - 5i) - (3 + 7i) }$

$\displaystyle \sf{ = 4 - 5i - 3 - 7i }$

$\displaystyle \sf{ = 4 - 3 - 5i - 7i }$

$\displaystyle \sf{ = 1 - 12i }$
