I’m not sure if I’m right
c(1)=c
cx1=c
c(n)=c(n-1)=c=0, n€R
cn=cx(n-1)
nc=cx(n-1)
nc=nc-c
0=-c
-c=0
c=0
c=0, n€R
hope this helps
Answer:
Step-by-step explanation:
So we want to simplify:
Note that this is in the format:
And we know that this is the same as:
Let 2√5 be a and let √3 be b. Thus:
Simplify:
And this cannot be simplified any further.
If you multiply -8 and -9 it's 72 because If you multiply two negatives it turns into a positive number/answer and if you add -8 and -9 it's -17.
-8 + -9 = -17
and
-8 * -9 = 72
