Veronika [31]

Answer:

x^6 y^3

Step-by-step explanation:

(x ^2 y)^3

We know that (ab)^c = a^c b^c

x^2^3 * y^3

We know that a^b^c = a^(b*c)

x^(2*3) y^3

x^6 y^3

Given A-<br> 2 2<br> 1 3<br> what is A-¹?

devlian [24]

The inverse of matrix A = $\left[\begin{array}{cc}2&2&1&3\\\end{array}\right]$ is $A^{-1} = \frac{1}{4}$ $\left|\begin{array}{cc}3&-2&-1&2\\\end{array}\right|$

The given matrix is A = $\left[\begin{array}{cc}2&2&1&3\\\end{array}\right]$

The inverse of a matrix is given by

$A^{-1} = \frac{1}{|A|} adjA$ ...(1)

Now, determinant of matrix A is

|A| = $\left|\begin{array}{cc}2&2&1&3\\\end{array}\right|$

= (3)(2) - (2)(1)

= 6 - 2

= 4

Now, adjoint A will be

$A_{11}$ = 3

$A_{12}$ = -1

$A_{21}$ = -2

$A_{22}$ = 2

AdjA = $\left|\begin{array}{cc}3&-2&-1&2\\\end{array}\right|$

Now, substituting the values of |A| and AdjA in equation (1), we get

$A^{-1} = \frac{1}{4}$ $\left|\begin{array}{cc}3&-2&-1&2\\\end{array}\right|$

Therefore, $A^{-1} = \frac{1}{4}$ $\left|\begin{array}{cc}3&-2&-1&2\\\end{array}\right|$
