1)
Проверка:
0² - 25 · 0 = 0 25² - 25 · 25 = 0
0 - 0 = 0 25² - 25² = 0
0 = 0 0 = 0
2)
Проверка:
0² + 25 · 0 = 0 (-25)² + 25 · (-25) = 0
0 + 0 = 0 25² - 25² = 0
0 = 0 0 = 0
3)
Проверка:
0² - 1,7 · 0 = 0 1,7² - 1,7 · 1,7 = 0
0 - 0 = 0 1,7² - 1,7² = 0
0 = 0 0 = 0
a^m^a^n = a^(m + n)
(a^m)^n = a^(mn)

⁵√a * a^4/5 = a^1/5*a^4/5 = a^(1/5 + 4/5) = a^1
⁶√x³ : x^1/2 = x*3/6 : x^1/2 = x^1/2 : x^1/2 = 1^1
∛(2^-1) ³ = (2^-1)^3*1/3 = 2^-1
(3³)^1/3 = 3^(3*1/3) = 3^1
