I hope this helps you
(a^2.4)(b^-3.4)
a^8.b^-12
So basically they want you to show 20 answers it already says 4 and you have to find the pattern in this one the pattern is add 6
2x - y = 5
x + 3y = 7
I'm assuming you mean the coefficient matrix.
![\left[\begin{array}{ccc}2&-1\\1&3\end{array}\right] =(2)(3)-(-1)(1)=6+1=7](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26-1%5C%5C1%263%5Cend%7Barray%7D%5Cright%5D%20%3D%282%29%283%29-%28-1%29%281%29%3D6%2B1%3D7)
It depends on the question given, for example
you can do distributive property will multiplying.
Example 1:
there is two ways on doing distributive property.
I can do 4(8+3)
add 8+3 since it is inside the parenthesis which equals = 11 then multiply the outside on what you added. 4x11= 44
example 2: I can also do it another way. 4(8+3) distribute the 4 by multiplying the 4 with both numbers. 4x8 and 4x3 which equals 32, and 12. add 32+12=44
so either way you will get the same answer. hope I helped.
