If z = 3 - 4i then what is |z|?
यदि z = 3 - 4i है तो |z| कितना होगा?
Show answer and explanation
C. 5 / 5
ExplanationStep 1: Use |a+ib| = √(a²+b²). Step 2: √(3²+(-4)²)=√25=5. Step 3: The modulus of a complex number works like distance from the origin.
Step 1: modulus formula |a+ib| = √(a²+b²) लगाएं। Step 2: √(3²+(-4)²)=√25=5। Step 3: complex number का modulus origin से दूरी जैसा होता है।
