A) B'AB is symmetric if A is symmetric.
B) B'AB is skew symmetric if A is skew symmetric.
C) B'AB is symmetric, if A is skew symmetric.
D) Both and
Correct Answer: D
Solution :
[a] Let a and x be the 1st term and common ratio of the G.P respectively. \[l=a{{x}^{p-1}}\Rightarrow \log a=loga+(p-1)logx\] \[m=a.{{x}^{q-1}}\Rightarrow logm=loga+\left( q-1 \right)logx\] \[n=a.{{x}^{r-1}}\Rightarrow \log n=\log a+(r-1)\log x\] \[=0+logx\times 0=0\] Hence, option [a] is correct.You need to login to perform this action.
