It is simply: 10n

yes
7*abs(n - 10) which is 7*(10 - n) if n < 10 and 7*(n - 10) if n ≥ 10
16(2^n)(10)(2^n)=160[2^(2n)]=160(4^n)
10 times n witch is a viatible
10n where n is positive is 10*10*10... n times [or 1 followed by n zeros] 10-n where n is positive is 1/10n = 1/(10*10*10...) n times [or 0.0...01 where there are n-1 zeros between the decimal point and the 1]
0.08
10 x n x n = 80 x n Divide by 10 x n; n = 8 Job done.
10000. Ten multiplied by itself n times is 1 followed by n zeros.
There are 4 terms
6787000 = 6.787 x 10^6, so for N x 10^9 = 6.787 x 10^6, divide both sides by 10^9, and N = 6.787 x 10^-3 = 0.006787
