Answer:
7 -1 6 | -8
7 -5 7 | 1
0 1 -4 | -5
Step-by-step explanation:
Note that there are four columns in this system, representing the variables x, y and z and constants. So the given matrix pattern is appropriate: It has three columns for the coefficients of x, y and z and one column for the constants.
We need only identify the coefficients and transfer them into the appropriate boxes of the matrix pattern.
We get:
7 -1 6 -8
7 -5 7 1
0 1 -4 -5

Step-by-step explanation:

Use the following formula (Difference of Two Squares)


We are not done yet. As we can still factor the expression which is x²-1 by using the same formula.

This is the fully factored form.
Answer:
One is 3 to 4th power
(3 x 3) x (3 x 3)
Step-by-step explanation:
the other is
3 to 3rd power divided by nine to the fourth power...
(3 x 3) x 3 = 27
(9 x 9 ) x (9 x 9) = 2187
2187 / 27 = 81
