Answer:

Step-by-step explanation:
Because of the power of a power property, which states that
, where m and n are real numbers, the expression you mentioned can be simplified by applying this property like this: 
DI/dx=-850x+45500
d2l/d2x=-850 so when dl/dx=0 it is an absolute maximum for l(x)...
dl/dx=0 only when:
850x=45500
x=53.53
x=54 years of age (rounded)
