Answer:

(104)³ = 1124800

Step-by-step explanation:

{\small{\tt{(104)^3}}}  \\ { \small{ \tt{ = {(100 + 4)}^{3} }}} \\ { \small{ \tt{ =  {(100)}^{3}  +  {(4)}^{3}  + 3(100)(4) (100 + 4)}}} \\ { \small{ \tt{=  1000000 + 64 + 1200(104)}}} \\ { \small{ \tt{ = 1000000 + 64 + 124800}}} \\ { \small{ \frak{ = { \underline  { \purple{  1124864}}}}}}

Identity used

  • (a+b)³ = a³ + b³ + 3ab(a+b)

Other identities

  • (a+b)² = a² + b² + 2ab
  • (a-b)² = a² + b² - 2ab
  • a² - b² = (a + b)(a - b)
  • (a-b)³ = a³ - b³ - 3ab(a-b)
  • a³+b³ = (a+ b)(a²-ab+b²)
  • a³-b³ = (a- b)(a²+ab+b²)
  • a³+b³+c³-3ab = (a+b+c) (a²+b²+c²-ab-bc-ca)
