2 3/50 : (-0.1)

1 5/6 + 5.6

2/7 * 1.4

(1,125-7/8) : (-0,5)

(3/8-0,875) * 10,2

(4-31/3) do potęgi 2

(1/2) - (3/2) do potęgi 2

(2/5)do potęgi 2 = (-1/2) do potęgi 2

pierwiastek4/25 - pierwiastek 25/4

pierwiastek 1 7/9 + pierwiastek 3 1/16

Bardzo proszę o odpowiedzi !! daję naj ! :D ;** ! z góry thx ; )

Answer 1

2 3/50 : (-0.1) =
= 103/50 : (-1/10) =
= 103/50 * (-10) =
= -103/5 =
= -20 i 3/5
============================

1 5/6 + 5.6 =
= 11/6 + 56/10 =
= 66/60 + 336/60 =
= 402/60 =
= 6 i 42/60 =
= 6 i 21/30
============================

2/7 * 1.4 =
= 2/7 * 14/10 =
= 2/5
============================

(1,125-7/8) : (-0,5) =
= (1 i 1/8 - 7/8) : (-0,5) =
= (9/8 - 7/8) : (-1/2) =
= 2/8 * (-2) =
= -2/4 =
= -1/2
============================

(3/8-0,875) * 10,2 =
= (3/8 - 7/8) * 102/10 =
= -4/8 * 102/10 =
= -1/2 * 102/10 =
= -51/10 =
= -5 i 1/10
============================

(4-31/3) do potęgi 2 =
= (4 - 31/3)² =
= (3 i 3/3 - 31/3)² =
= (12/3 - 31/3)² =
= (-19/3)² =
= 361/9 =
= 40 i 1/9
============================

(1/2) - (3/2) do potęgi 2 =
= 1/2 - 9/4 =
= 2/4 - 9/4 =
= -7/4 =
= -1 i 3/4
==================================

(2/5)do potęgi 2 = (-1/2) do potęgi 2 =
= 4/25 - 1/4 =
= 0,16 - 0,25 =
= -0,09
=====================================

√4/25 - √25/4 =
= 2/5 - 5/2 =
= 0,4 - 2,5 =
= - 2,1
=====================================

√1 7/9 + √3 1/16 =
= √16/9 + √49/16 =
= 4/3 + 7/4 =
= 16/12 + 21/12 =
= 37/12 =

= 3 i 1/12
