PLEASE HELLP 25 POINTS

Hello from MrBillDoesMath!

Answer:

a^6 + 4 a^5 + 5 a^4 - 5 a^2 - 4 a - 1


Discussion:

You may need to clean things up a bit but suppose that

S(1) = a-1

S(2) = a^2 -1

Since this is a geometric series, the geometric ratio is given by


S(2)/ S(1) =  (a^2 -1)/ (a-1)

               =  (a+1)(a-1)/ (a-1)

               = a+1

Conclusion:

S(2) = (a+1) S(1) = (a+1) (a-1)

S(3)  = (a+1) S(2) = (a+1) (a+1) (a-1)   = (a+1)^ (3-1) (a-1)

S(4) = (a+1) S(3)  = (a+1) * (a+1)^2 (a-1) ) = (a+1)^(4-1) (a-1)

in general.....

S(n) = (a+1)^ (n-1) (a-1)

So

S(6) = (a+1)^ (6-1) (a-1)

      =  (a-1) (a+1) ^ 5

     =  a^6 + 4 a^5 + 5 a^4 - 5 a^2 - 4 a - 1


Hope I didn't screw something here!


Thank you,

MrB

8 • 10 exponent 9 ÷ 1.2 • 10 exponent 6
Alex_Xolod [135]
Ok 12÷9=0r12 and with exponits 10 and 10 because 10 and 10 will become 10 and 6 so 12+10=22 now you can divide 22÷9=1R3

Math ... answer meeee
zloy xaker [14]

You need to find the GCF (greatest common factor) of 45 and 90, which is 45.

45 times ? gets you 45

? would be 1

45 times 1 equals 45.

45 times ? gets you 90

? would be 2

45 times 2 equals 90

45(1+2) = 45+90 = 135

♡ Hope this helps! ♡
