if `A[{:(5,-3),(111,336):}]` and det`(-3A^(2013)+A^(2014))=alpha^(alpha)+beta^(2)(1+gamma+gamma^(2))` where `alpha,beta,gamma` are natural numbers and `(alphagtgammagtbeta)` then

A

`alpha+beta=2016`

B

`alpha+beta=2023`

C

`alpha+beta+gamma=2026`

D

`beta+gamma=13`

Text Solution

Verified by Experts

The correct Answer is:
A, C, D

`because-3A^(2013)+A^(2014)=A^(2013)(A-3I)`
`becausedet(-3A^(2013)+A^(2014))=|A^(2012)(A-3I)|`
`=|A|^(2013)|A-3I|=(2013)^(2013)(999)`
`(2013)^(2013)3^(2)(1+10+10^(2))`
