Scientific notation is the representation of a number in a power of ten, with a sequence of digits placing the comma after the first digit, and the power or then that is mathematically consistent with the number. For example 400 is 4.00 * 10^2; 3100 is 3.100 * 10^4; 13421 = 1.3421 * 10 ^4. It is important that you have only one digit before the comma. So, 5,098,00 is 5.098 * 1,000,00 = 5.098 * 10^6. <span>The answer is the option c. 5.098 * 10^6.</span>
        
             
        
        
        
The answer is C. Use the quadratic formula to solve it and you should be just fine!
        
                    
             
        
        
        
Answer:
c = 40d+20
Step-by-step explanation:
He has to pay 20 dollars and that can't multiply so the forty has to multiply and it would have to be by d because c is the total cost
 
        
                    
             
        
        
        
The answer is the third one
        
             
        
        
        
It is called a complex number.
