Ответ:
135/32
Пошаговое объяснение:
(3/2)³-(-1/2)²÷(-2/3)³=(3/2)³(1-(-1/2)²)=(3/2)³(1+1/4)=27/8*5/4=135/32
в) (1 1/2)³ - (- 1/2 )² : ( - 2/3)³ = 4 7/32
¹ ⁵ ² ⁴ ³
1) (1 1/2)³ = ( 3/2)³ = 27/8 = 3 3/8
2) (- 1/2 )² = 1/4
3) ( - 2/3)³ = - 8/27
4) 1/4 : (-8/27) = 1/4 * (- 27/8) = - 27/ 32
5) 27/8 - (-27/32) = 27 * 4 / 8 * 4 + 27/ 32 = 108 + 27 / 32 = 135/32 = 4 7/32
