Answer 1

Объяснение:

а) 3 ³√64 + 4 ⁵√(-32) + ⁴√256 =

= 3 ³√(4)³ + 4 ⁵√(-2)⁵ + ⁴√(4)⁴ =

= 3*4 + 4*(-2) + 4 = 4 ( 3-2+1 ) = 3*2 = 6

б) ( 1/4² * 81^(-1)) ^(-1/4) =

= (1/4² * 1/81) ^ (-1/4) =

= 1 / (1/4² * 1/81)^(1/4)=

= 1/ ⁴√(1/(4²*81)) =

= 1/ ⁴√(1/(2⁴*3⁴)) =

= 1/ (1/(2*3)) = 1 / (1/6) = 1 * 6/1 = 6
