Answer:
Z^-26
Step-by-step explanation:
Because the base number is the same you are going to leave it the same.
Because it is multiplication you are going to add the powers
Because they are negative you will subtract the powers.
Z^-11 + (- Z^-15)
Therefore, you answer is z^-26
(FYI the -26 is a power)
Answer:
I think it should be 11/3
On opening the brackets;
x-3-2x+12=-5
Putting like terms together;
x-2x-3+12=-5
-x+9=-5
-x=-14
x=14
It would be log(81) because of the power rule...
