 Answer:
5 
Step-by-step explanation:
Assuming we want to evaluate |z|, given that, z=4+3i.
Then, by definition of modulus,



Therefore the modulus be of the given complex number is 5 units
 
        
             
        
        
        
Answer: x = 1
 x =(-3-√-15)/4=(-3-i√ 15 )/4= -0.7500-0.9682i
 x =(-3+√-15)/4=(-3+i√ 15 )/4= -0.7500+0.9682i
 x2 = 0
Step-by-step explanation:
 
        
             
        
        
        
Is that even an actual equation?
        
             
        
        
        
You cross multiply. So 61 over 18 = x over 100. You multiply 61 and get the answer of 1600. Now with what you have left, you divide that with 18 and you should get your answer of <span>338.888889. Make sure to round it to whatever it tells you to round to!</span>
