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.
Answer:
Step-by-step explanation:
I think you meant 3([7/5]x + 4) - 2(3/2 - [5/4]x). If that's the case, then identify the LCD: It is 20. Multiply both [7/5]x + 4 and 3/2 - [5/4]x by 20 and then divide the resulting expression by 20:
3(28x + 80) - 2(30 - 25x)
------------------------------------
20
Next, perform the indicated multiplication:
84x + 240 - 60 + 50x
----------------------------------
20
This simplifies to:
34x + 180 17x + 9
---------------- = ----------------
20 10
