1) а) = 1/3 - 4/3 + 4 = 3
б) = √(3¹²*4⁶) = 3⁶*4³ = 729*64 = 46656
2) разность квадратов
= ⁴√х² - 4 ⁴√у² + 2 ⁸√у⁷ : ⁸√у= √х - 4√у + 2 ⁸√у⁶ = √х - 4√у + 2 ⁴√у³
3) ⁵√(243m⁵) +⁴√(16cm⁴) = 3m + 2m√c - 6m = -3m + 2m√c =
= -3*(-1/7) + 2*(-1/7)√c = 3/7 - 2/7*√с
4) 2⁻³ = 1/8
(1/32)^1/5 = 1/2
(2^5/3 - 1)(2^10/3 + 2^5/3 +1) = 2⁵ - 1 = 32 -1 = 31
