Calculate the value for each determinant:

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

$\begin{vmatrix}3 & -1\\ -3 & 4\end{vmatrix}=(3\times 4)-(-1)\times (-3)$

= 12 - 3

= 9

$\begin{vmatrix}8 & -1\\ -4 & -1\end{vmatrix}=8\times(-1)-(-1)\times(-4)$

= -8 - 4

= -12

$\begin{vmatrix}-12 & -1\\ 12 & 5\end{vmatrix}=(-12)\times(5)-(-1)\times(12)$

= -60 + 12

= -48

$\begin{vmatrix}2 & -1\\ 2 & -1\end{vmatrix}=2\times(-1)-(2)\times(-1)$

= -2 + 2

= 0

$\begin{vmatrix}0 & -1\\ 17 & 4\end{vmatrix}=0\times(4)-(-1)\times(17)$

= 17

$\begin{vmatrix}1 & 0\\ 0 & 1\end{vmatrix}=1\times(1)-(0)\times(0)$

= 1

Put the 2 as an exponent of 12: log3(12)^2=log3(144)
log3(144)-log3(16)=log(144/16)=log3(9)=2

logx^2+log(x+1)^(1/2)-logy^3
=2logx+(1/2)log(x+1)-3logy
refer to another of your questions that I just answered.
