Hi!
Alrighty, so there are 5 sets of 50 in 250 (250 divided by 50), so just take 50 times 12 and get 60! Hope that helped :)
Answer:
cf=f*points
Step-by-step explanation:
30*1=30
40*2=80
50*4=200
60*3=180
70*3=210
80*5=400
90*6=540
total=sum of all
Let the first term be a(0). Then the formula for a(n) is a(0)-18(n-1).
Check: What's the first term? Let n = 1: a(1) = a(0)-18(1-1) = a(0) (correct)
What's the second term? Let -n =2: a(2) = a(0)-18(2-1) = a(0) - 18
and so on.
Answer: There are 6046 digits will be written on expansion upto 2015th power.
Step-by-step explanation:
Since we have given that

We have to find the number of digits ,
So,

Since we know that

so,

Hence, there are 6046 digits will be written on expansion upto 2015th power.
