Answer & Solution

Correct Answer

(C) \(10^{10}-2\)

Step-by-step Solution

Detailed explanation

(c) Given \(0 < x < 10\) \[ \Rightarrow 1 < 10^x < 10^{10} \] Let \(0 \leq x \leq 1\) then \(\left[10^x\right]\) will have to points of discontinuity But when \(0 < x < 1\) the \([10 x]\) will have only \(\left(10^1-2\right)=8\) points of discontinuity because we are leaving…
