9e + 4 = 14 + 8e
9e = 10 + 8e (Subtract 4 from both sides)
e = 10 (Subtract 8e from both sides)
30! equals 2.6525286e+32
30 is a natural number
! is a factor
There are a couple of ways you can solve this. You can write it out like
(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)
And pretty much use the foil method
Or you can use the binomial theorem (google it if you dont know)
The solution should be:
(K^7) - 21(k^6) + 189(k^5) - 945(k^4) + 2835(k^3) - 5103(k^2) + 5103k - 2187
You divide -15 on both sides to keep the x alone
-240/ -15=16
A negative divided by a negative is a positive so x=16
