Note how the 4th difference column is all 24 - 4th derivative of x^4 = 24
8^log_8(x) = x
exponentiation and logs are inverse operations.
b^log_b(x) = log_b(b^x) = x
the definition of log(N) is the power you need to get N, whatever the base.
and that's "to whoever answers". "whoever answers" is a noun phrase, used (as a unit) as the object of the preposition. A common mistake.
I'm confused on how to do this.
1.) Show that f(x)=x^4 -2x +8 has nonzero constant fourth-order differences.
SIMPLIFY THE EXPRESSION: (HOW?)
2.) 8^log(8)^x
eight log root 8 ^x (here it is written if you can't understand the actual expression. It is definitely hard typing this out cuz I do not know if you could understand this/ to whomever answers.)
