=0,875-2,5- 0,5 +3=
=0,875-3 +3= 0,875
7/8 = 0,875
1) 8,5 * 8⁻⁴/³ = 8½ : 8⁴/₃ = 17/2 : 8³/³ *8¹/³ = 17 : (2*8*∛8) = 17 : (2*8*2) = 17/32
2) (-2)⁻⁵ = 1 : (-2)⁵ = - 1/32
3) 27¹/³ = ∛27 = 3
4) 7/8 - 2½ - 17/32 - (-1/32) + 3 =
= 7/8 - 2½ - 16/32 + 3 = 7/8 - 2½ - ½ + 3 = 7/8
7/8 * 125/125 = 875/1000 = 0,875
