POPRAWIONE ZADANIE a)
a. (2/5)^7 x 2,5^6 =.....
= (2/5)^7 * (5/2)^6 =
=(2/5)^7 *(2/5)^(-6) =
= (2/5)^1 =
2/5
b. 1/2 pierwiastek z 3 x pierwiastek z 3 /4 = .....
= 1/2*√3*√3 /4 =
= 1/2*3 :4 =
= 3/2 *1/4=
= 3/8
lub jeżeli jest: 1/2*√3 *√(3/4) =
= 1/2*√3*√3 : *√4 =
= 1/2*3 :2 =
= 3/2*1/2=
= 3/4
c. 3+6pierwiastek z 5 /3 = ....
= 3 + 6*√(5/3) =
= 3 + (6*√5 ):(√3)=
= 3 + (6*√15 ):3 =
= 3 + 2*√15
lub jeżeli jest: (3 + 6*√5) :3 =
= 1 + 2*√5
lub jeżeli jest 3 + (6*√5):3 =
= 3 + 2*√5
a)
(2/5)^7 * 2,5^6 =(2/5)^7 *(25/10)^6 =(2/5)^7 *(5/2)^6 =
= (2/5)^7 *(2/5)^(-6) =(2/5)^1 =2/5
b)
1/2V3 *V3/4 =1/2V3 *V3:4 =3/2:4 =3/2 *1/4 =3/8
c)
(3+6V5)/3 =3/3 + 6V5/3 =1 +2V5
