PLEASE HELP ASAP!! Evaluate the expression for x=-2. No decmial values in answer. 1/x/x^4.

 

Evaluate the expression for x=-2. No decmial values in answer. 1/x/x^4. The answer is -1/32 but i dont know how to solve it i keep getting 8 please help and explain what i did wrong. This is using exponent rules! Thank you so much! :)   

 

    1                              x⁴  

———   divided by   ———  

    x                              1  

 

To divide by a fraction, invert the divisor and multiply.  

 

    1                                1     

———   multiplied by  ———  

    x                                x⁴     

 

    1                                1     

———   multiplied by  ———  

  –2                              (–2)⁴     

 

    1             1     

———  •  ———  

  –2            16  

 

Take it from there.
