Вычислить:
1) √0,25 = 0,5;
2) = 2;
3) ∛-3 3/8 = ∛27/8 = 3/2 = 1,5;
4) 0,7* = 0,7*3 = 2,1;
5) = 2/3;
6) (2∛4)³ = 2³*4 = 8*4 = 32;
7) 6/(2√3)² = 6/2²*3 = 6/12 = 0,5;
8) -3* = (-3) * (-7) = 21;
9) * = 2 * (-5) = -10;
10) * ∛0,008 = 1 * 0,2 = 0,2;
11) ;
12) ∛54 * ∛32 = ∛54*32 = ∛1728 = 12;
13) ∛189/3*∛7 = 1/3 * ∛189/7 = 1/3 * ∛27 = 1/3 * 3 = 1.
