333. Упростите выражение:
2.
( 2√(2/3) - 8√(3/8) +3√(3/2) )* 3√(3/2)
=2*3√( (2/3) *(3/2) ) -8*3√( (3/8)*(3/2) ) +3*3√( (3/2) )* (3/2) ) =
6 - 8*3*(3/4) +9*3/2 = 6 -18 +13,5 = 1,5.
4.
(7√8 -14√18 +0,7√12 ) : 7√2 =
( (7√8) : 7√2 ) - (14√(18) : 7√2 ) + (0,7√12 ) : 7√2 ) =√4 -2√9 +0,1√6
= 2 -6 + 0,1√6 = - 4+ 0,1√6 . || - 4+ √0,06 ||

2.
(x³ -3x) / (x+√3) = x(x² -3) / (x+√3) = x(x -√3)(x+√3) / (x+√3) = x(x -√3).
4.
(4√a +√b) / (b - 16a)=(4√a +√b) / ( (√b)² - (4√a)² ) =
(4√a +√b) / ( b - 4√a)( b +4√a) = b - 4√a.
