Step-by-step explanation:
a) 1.16× 10^-6
standard form should be less than 10. therefore, count decimal places from where the decimal point is located to the right until you reach a number less than 10 ....count the number of shifts in the above is 6 shifts to the right. when moving to the right, power will be negative.(-6)
1.157/1.16 ×10^-6
b) 6.79 × 10^10
67890000000....count till a number less than 10.there will be 10 shifts to the left. the 10 will be your power,(positive) since u r moving to the left exponent is positive 
6.789/6.79 × 10^10
 
        
                    
             
        
        
        
For this case we have the following polynomial:
 
 We make the following change of variables:

 Rewriting we have
 
 Factoring the second order polynomial we have:

 Then, returning the change we have:

 Finally, we factor the expression in the parentheses of the second term:

 Answer:
 the completely factored form is:
