Solving the given equation, we have:
10^(a + b + c) = 10^6
a + b + c = 6
Since a, b and c are different positive integers, they must be 1, 2, and 3 (in any order). For example, if a = 1, b = 2 and c = 3, 10^a + 10^b + 10^c = 10 + 100 + 1000 = 1110.

Given that \(10^a*10^b*10^c=1,000,000\) and a, b, and c are different positive integers and we need to find the value of \(10^a+10^b+10^c=\)
\(10^a*10^b*10^c=10^6\) => \(10^{a + b +c}=10^6\) => a + b + c = 6 Since, a, b, c are distinct positive integers so they will take values from 1, 2, and 3 => \(10^a+10^b+10^c\) = \(10^1+10^2+10^3\) = 10 + 100 + 1000 = 1110
So, Answer will be D Hope it helps!
