Question

Find the modulus of z = 2-3i​
solve this by step by step

Answer 1

Answer:

Step-by-step explanation:

We have,

$\tt{z=2-3i}$

$\sf{We\,\,know,\,\,for\,\,a\,\,complex\,\,number\,\,z=x+i\,y}\\\sf{Its\,\,modulus\,\,is\,\,given\,\,by\,\,\green{|z|=\sqrt{x^2+y^2}}}$

So,

$\sf{|z|=\sqrt{(2)^2+(-3)^2}}$

$\sf{\implies\,|z|=\sqrt{4+9}=\sqrt{13}}$
