Answer 3

Ta có \(3^2.10^3-\left[13^2-\left(5^2+4+2^2+15\right)\right]10^3\)

          \(=9.1000-\left[169-\left(25+4+4+15\right)\right]1000\)

           \(=9.1000-\left(169-48\right)1000\)

           \(=1000\left[9-\left(169-48\right)\right]\)

            \(=1000.\left(-112\right)\) 

              \(=-112000\)
