If z = 5 - 12i then what is the modulus of z?
यदि z = 5 - 12i है तो z का modulus क्या होगा?
Show answer and explanation
Correct Answer
C. 13
ExplanationStep 1: Use modulus formula |a+ib|=√(a²+b²). Step 2: |5-12i|=√(25+144)=√169=13. Step 3: In modulus the sign of imaginary part does not matter after squaring.
Step 1: Modulus formula |a+ib|=√(a²+b²) लगाएं। Step 2: |5-12i|=√(25+144)=√169=13। Step 3: Modulus में imaginary part का sign square होने पर असर नहीं करता।
