Answer:
Raising something to a negative exponent is just taking the reciprocal of the amount.
Step-by-step explanation:
Let's assume that you wanted to know what  is.
 is. 
To find it, you would take the reciprocal of the x amount. So  becomes
 becomes  .
. 
This works because of the nature of exponents. Exponents represent the number of times you are multiplying a value by itself. So  would be equal to a · a · a. To increase the exponent, you increase the number of times the value is multiplied by itself: To increase
 would be equal to a · a · a. To increase the exponent, you increase the number of times the value is multiplied by itself: To increase  to
 to  , you would have to multiply a with
, you would have to multiply a with  two more times (a · a · a · a · a). To decrease the exponent, you must divide the value by itself. So to decrease
 two more times (a · a · a · a · a). To decrease the exponent, you must divide the value by itself. So to decrease  to
 to  , you would have to divide
, you would have to divide  by a 3 times.
 by a 3 times. 
If the exponent is 0, the value is equal to 1. But you can still decrease the exponent into negative numbers. You just divide 1 by a the desired amount of times:  means that you are dividing 1 by a 3 times.
 means that you are dividing 1 by a 3 times. 
Hope this helps.
 
        
             
        
        
        
1) Let's solve for x, writing this equation.
3x +8*59 =0
3x +472=0 <em>Subtract 472 from both sides</em>
3x = -472
x= -472/3 or -157.33
2) So the answer is x= -472/3

Answer:

Step-by-step explanation:
An asymptote of a vertical line is one that the graph can't exactly reach, but can get as close as you want it to be (as long as the distance is not 0), while the x- or y-coordinates tend to plus/minus infinity. An example of where this happens is when filling in the x-value would result in a zero in the denominator, hence the answer.
