换元法大家都不陌生,均值换元法初中生也偶有接触,本文就均值换元解某些高次方程略举两例.例1 在实数范围内解方程(x-5)~4+(x+1)~4=272.
The substitution method is not unfamiliar to us, and the mean value substitution method junior high school students have occasional contact. In this paper, two equations are used to solve some high-order equations for mean value conversion. Example 1 Solution of the equation (x-5)~4 in the real number range +(x+1)~4=272.
