Can someone please simplify ln e^4/8 showing me how to do it

Otrada [13]

Answer:

e ^1/2

Step-by-step explanation:

All you do is take the fraction (4/8) and just simplify that part

4 divided by 2 = 2

8 divided by 2 =4

I got 2/4 but I can simplify more

2 divided by 2= 1

4 divided by 2 = 2

Now I got 1/2

And I would just leave e alone so my answer is e ^1/2

Do you kinda get what im saying?

Transfer transfer the system of equations by forming a matrix equation.

Anika [276]

Answer:

Step-by-step explanation:

$\begin{bmatrix}2 & -3\\ 1 & 2\end{bmatrix}^{-1}\times \begin{bmatrix}2 & -3\\ 1 & 2\end{bmatrix}\times \begin{bmatrix}x\\y \end{bmatrix}=\frac{1}{7} \begin{bmatrix}2 & 3 \\ -1 & 2\end{bmatrix}\times \begin{bmatrix}19\\ -1\end{bmatrix}$

Since, $\begin{bmatrix}2 & -3\\ 1 & 2\end{bmatrix}^{-1}=\frac{1}{7}\begin{bmatrix}2 & 3\\ -1 & 2\end{bmatrix}$

And $A^{-1}A=I$

$\begin{bmatrix}x\\y \end{bmatrix}=\frac{1}{7}\begin{bmatrix}2 & 3\\ -1 & 2\end{bmatrix}\times \begin{bmatrix}19\\-1 \end{bmatrix}$

$\begin{bmatrix}x\\y \end{bmatrix}=\frac{1}{7}\begin{bmatrix}35\\ -21\end{bmatrix}$

$\begin{bmatrix}x\\y \end{bmatrix}=\begin{bmatrix}5\\ -3\end{bmatrix}$

Therefore, x = 5 and y = -3 will be the value of variables.
