For statements that is correct, type 1. For statements that is incorrect, type 2. For statements that is partially correct, type 3. So the answer is a 10-digit number  1) $$\sqrt [ 3 ]{ 27 } \quad -\quad \sqrt { 9 } \quad =\quad 0$$  2) $$\log { 10 } \quad \times \quad \log { 100 } \quad =\quad \log { 1000 }$$  3) $${ x }^{ 2 }\quad -\quad 2x\quad -\quad 3\quad =\quad 0$$ has the factors $$x\quad =\quad -1$$ and $$x\quad =\quad 3$$  4) $${ 999 }^{ 999 }$$ is divisible by 3  5) Since $$10!$$ has 2 trailing zeros, and $$20!$$ has 4 trailing zeros, $$10! + 20!$$ has 6 trailing zeros  6) $$sin\quad { 2460 }^{ \circ }\quad =\quad sin\quad { 300 }^{ \circ }$$  7) If $$f\left( x \right) \quad =\quad \frac { ax\quad +\quad b }{ cx\quad +\quad d }$$, then $$f^{ -1 }\left( x \right) \quad =\quad \frac { -dx\quad +\quad b }{ cx\quad -\quad a }$$  8) $$\sqrt [ 4 ]{ x } \quad \times \quad \sqrt [ 4 ]{ x } \quad =\quad \sqrt { x }$$  9) $$\lim _{ n\quad \rightarrow \quad 1 }{ \frac { { n }^{ 2 }\quad -\quad 1 }{ n\quad -\quad 1 } } \quad =\quad 2$$  10) $$\frac { \sqrt [ 10 ]{ 10 } }{ \log _{ 10 }{ 10 } } \quad =\quad \frac { 5 }{ 2 } \pi$$
