3⁴⁰⁰ - 3³⁹⁸ =
3³⁹⁸ (3² - 1) =
3³⁹⁸ (9 - 1) =
3³⁹⁸ (8)

Whatever 5^2.5 is. 25√5. Something like 56?
--------------------------------------
f(x+4)=f(x+2)+6=f(x)+2*6
Thus, f(x+2n)=f(x)+6n
Since f(1)=7, then f(2021)=f(1)+1010*6=6067.

9x³ - x⁶ = 8
X = ?
نخرج x³ عامل مشترك
ونحل المعادلة فالناتج يكون اما X=2
او X=1
