A) \[10\]
B) \[-10\]
C) \[-1000\]
D) \[1000\]
Correct Answer: D
Solution :
\[\det \,\,A=1,\] \[\det \,\,B=-1\] \[\det \,(-10AB)={{(-10)}^{3}}\,\det \,(AB)\] \[[\because \,\,\det \,(kA)\,={{k}^{n}}\,\det \,(A)]\] (here, \[n=3\]) \[=-1000\,\det \,(A)\,\det \,(B)\] \[=1+\log \,abc\]You need to login to perform this action.
