I count five 'k's there, so that part of the expression is
                                     k⁵  .
Two 'n's form the rest of it, so that part is  n² .
The parts are multiplied, so the simplest form of the expression is
                                     k⁵ n²  .
        
             
        
        
        
Answer
The initial temperature was T = -7 degrees
Step-by-step explanation:
Let the initial temperature be T.
- The tempature was very cold
Temperarure = T
- Then it doubled
Temperature = 2T
- Then it dropped 10 degrees
Temperature = 2T - 10
- And then it increased by 40 degrees.
Temperature = 2T - 10 + 40 = 2T + 30
The tempature is now 16 degrees
Temperature = 16 degrees
2T + 30 = 16
2T = -14
T = -7 degrees
Hope this Helps!!!
