Answer:
   84x^10
Step-by-step explanation:
The coefficients multiply, and the exponents add.
   (4x)( -3x^6)(-7x^3) = (4)(-3)(-7)x^(1+6+3) = 84x^10

The rule for exponents is ...
   (x^a)(x^b) = x^(a+b)
 
        
             
        
        
        
500/4= 125

Answer:
Step-by-step explanation:
<u>Given polynomial:</u>
- x¹⁹ + x¹⁷ + x¹³ + x⁷ + x⁵ + x³
<u>Group as follows:</u>
- (x¹⁹ + x¹⁷) + (x¹³ + x¹¹) + (x⁷ + x⁵) + (x³ + x) - x = 
- x¹⁷(x² + 1) + x¹¹(x² + 1) + x¹⁵(x² + 1) + x(x² + 1) - x
As we see all terms have (x² + 1) as factor apart from the last one.
It means the remainder is - x
Correct choice is C
