Commutaitve has to do with moving around the order
it is a+b=b+a
so x+5=5+x, therefor
9(x+5)=9(5+x)
Answer:
Two ways you can group them is:
(4+7)+2
4+(7+2)
They will both give you the same answer of 13.
(4+7)+2 4+(7+2)
11+2= 13 4+9= 13
we have that
A+B=B+A -------> is the same
so
B+A= (1-5) (-3+3) (4-5) (-5-2)
(2-4) (5-2) (-4+4) (4-5)
<h2>B+A= -4 0 -1 -7</h2><h2> -2 3 0 -1</h2>
SOLUTION
We have been given the equation of the decay as

So we are looking for the time
Plugging the values into the equation, we have

Taking Ln of both sides, we have

Hence the answer is 4308 to the nearest year
