सारणिकों के गुणधर्मों का प्रयोग करके मूल्यांकन कीजिए - `|(1,3,9,27),(3,9,27,1),(9,27,1,3),(27,1,3,9)|`

Evaluate |(1,3,9,27),(3,9,27,1),(9,27,1,3),(27,1,3,9)|

Evaluate the determinant by expanding ,1,3,9,273,9,27,19,27,1,327,1,3,9]|

1/3,4/9,7/(27),(10)/(81),?,(16)/(729)

1/3,1/9,1/(27),….a_7

If A= [ (1,3,9,27 ), (3,9,27,1),(9,27,1,3),(27,1,3,9)] then det A= (A) 0 (B) -(80^3) (C) (80^3)27 (D) 81^3

If A=[91,3,9,27),(3,9,27,1),(9,27,1,3),(27,1,3,9)] then det A= (A) 0 (B) -80^3 (C) 80^3 (D) 81^3

If A= [ (1,3,9,27 ), (3,9,27,1),(9,27,1,3),(27,1,3,9)] then det A= (A) 0 (B) -(80^3).27 (C) (80^3)27 (D) 81^3

1-(3)/(1!)+(9)/(2!)-(27)/(3!)+....=

Solve: 9xx81^(x)=(1)/(27^(x-3))
