Question

Chodzi o te przykłady:c,d,e,f

Nie trzeba wszystkich chociaż jdeno albo dwa.Proszę o pomoc bo to na jutro.Blagam!!!!!!!

Answer 1

c)

=[√25/4 * 1/2 *1]/[-8:(-0,8)-(45/10 * 5/2):2]=

=[5/2 * 1/2]/[10 - 15/2 * 1/2]=

=[5/2]/[40/4 - 15/4]=

=5/2 : 25/4=

=5/2 * 4/25=

=2/5

=====================================

e) 

=[-2/3 * 9/8 * 4/3]/[1/2 : 5/4] + 2,5=

=[-1]/[1/2 * 4/5] + 2,5=

=-1 : 2/5 +2,5=

=-1 * 5/2 +2,5=

=-25/10 +2,5=

=-2,5+2,5=

=0 

=====================================

d)

={-5/4 - [-45/10 * 5/9 + 64/10 * 3/8]/[-12/10 : (-3/10)]} : (3*1/5)=

={-5/4 - [-25/10 + 24/10]/[12/10 * 10/3]} : (3/5)=

={-5/4 - [-1/10 : 4/10]} * (5/3)=

={-5/4 - [-1/10 * 10/4]} * (5/3)=

={-5/4 - (-1/4)} * (5/3)=

={-5/4 + 1/4} * (5/3)=

=-1  * (5/3)=

=-5/3

=====================================

f)

=[1/2 * 3 * 5/3 * 10/25]/[-(6/6 -19/6)² * (13/6)⁻¹] * (26/100)=

=[1]/[-(-13/6)² * 6/13] * (26/100)=

=1/[- 169/36 * 6/13] * (26/100)=

=1 : (-13/6) * (26/100)=

=1 * (-6/13) * 26/100=

=-3/25
