Using the product rule to show that $(fgh)' = f 'gh + fg' h + fgh'
2015年2月23日 · By the generalized product rule just proven, you can simply state that $$ (fghj)' = f'ghj + fg'hj + fgh'j + fghj' $$ without going into messy algebraic manipulations like all of the answers here have done (including my answer to your specific problem).

Proving f (gh) = (fg)h - Mathematics Stack Exchange
I am trying to prove that $f(gh)=(fg)h$ for $f,g,h \in R[\mathbb{N}^n]$. Context to the exercise: We define the polynomial ring $R[X_1,...,X_n]$ in $n$ variables as $$ R=[X_1,...,X_n] = R[\mathbb{N...
大数入门(1)——FGH与基本列 - 123789456ye - 博客园
2023年12月7日 · 与FGH的形式类似,我们严格定义基本列(fundamental sequence)如下(Wainer Hierarchy): 一切伟大的行动和思想,都有一个微不足道的开始。 There is a negligible beginning in all great action and thought. 虽然是英文但是讲的不错,稍微翻译一下罢(虽然已经有挺多人写过这个了) 网站 说起来发明FGH这个标尺的确实是神,简洁明了 前置知识 超运算 这倒是非常自然的想法 若将加法看作第一级运算,乘法看作第二级运算,乘方看作第三级运算, …
linear algebra - Showing that if $fg=gf$ and $fh=hf$, then $gh…
Given real numbers a and b (a ≠ 0), let fa, b be the function R → R defined by x ↦ ax + b. The set of such functions is a permutation group on R, under function composition. Let f, g, h, ∈ G, where f is not the identity. If f commutes with both g and h, show that g and h commute with each other. (Problem from I.M. Isaacs)
