Answer:
3400
Step-by-step explanation:
60 * 70 = 4200
70 - 10 - 20 = 40
20 * 40 = 800
4200 - 800 = 3400
Again take the variable to be x
x^12-15
Answer:
0.707
Step-by-step explanation:

Ok to create a number less than 3 hundred thousand, 7 ten-thousands, 5 thousands, 2 hundreds and 1 ten, we need to know the place values of large numbers.
If it is less than 3 hundred thousand:
There would be 6 decimal places or: > 300,000
7 ten thousands:
70,000
5 thousand:
5,000
1 ten:
10
Join together all these numbers to get something like:
275,010
