Answer:
and a₁ =30000 for n = 2,3,4,5,6, ......
Step-by-step explanation:
Doug has joined a job with a starting salary of $30000 per year.
Hence, if a₁ is the salary of Doug in the first year, then
a₁ =30000
Now, each year Doug will receive a raise of $3000 in his salary.
Hence, in the 2nd year, his salary(a₂) will become ( a₁ +3000) per year.
Again, in the 3rd year, his salary(a₃) will become ( a₂ +3000) per year.
Therefor, in the similar manner the recursive formula for his salary in each year will be given as and a₁ =30000 for n = 2,3,4,5,6, ...... {aₙ is the yearly salary of Doug in the nth year} (Answer)
Answer:
+
Step-by-step explanation:
We sure can write 2^2/5+ 3^1/10 as
// use the to transform the expression
Convert to
=
(here a = 2, n = 5, m = 2)
Then convert to
=
(here a = 3, n = 10, m = 1)
Now we get =
+
. This is the simplified form, which is the answer.
