Question

Zapisz w jak najprostszej postaci.

a) 5 √13 x (-0,4)

b) 5/6 √3 x √3/2

c) (4√3)do kwadratu + (√2)do kwadratu

d) (3x√5)do kwadratu/(5 √3) do kwadratu

Answer 1

a) .... = 5 * (-0,4) * √13 = -2√13

 

b)...... = 5/6 * 1/2 * √3 * √3 = 5/12 * 3 = 5/4 = 1 i 1/4

 

c)  ..... = 16 * 3 + 2 = 48 + 2 = 50

 

d) ... = 9 * 5 + 25 * 3 = 45 + 75 = 120

lub

..... = 9 * 5 - 25 8 3 = 45 - 75 =  - 30
