Solve for x:
250 = 53.0918 x

 

250 = 53.0918 x is equivalent to 53.0918 x = 250:
53.0918 x = 250

 

Divide both sides of 53.0918 x = 250 by 53.0918:
(53.0918 x)/53.0918 = 250/53.0918

 

53.0918/53.0918 = 1:
x = 250/53.0918

 

250/53.0918  =  4.70882:
Answer: |  x = 4.70882

I'm taking this to be :

 

250=50e^[0.06x]  divide both sides by 50

 

5 = e^[0.06x ]  take the natural log of both sides

 

ln 5 = ln  e^[0.06x ]  and we can write this as

 

ln 5 = [ 0.06x ]* [ ln e  ]      and ln e = 1  .....  so we can ignore this

 

ln 5 =  0.06x     divide both sides by 0.06

 

ln5 / 0.06 =  about  26.824

 

 

cool cool cool
