Zadanie macie w załączniku i winik musi wynościć -1
Daje naj!
(-1/14)^-5 : (1/7)^-5 * (0,5)^-5 = (-1/2)^-5 * (1/2)^-5= (-1/4)^-5 =- 4^5 (-tyle bedzie u gory a na dole
2^-5 :8^-5 = (1/2)^5 : (1/8)^5 = (1/2 : 1/8)^5 = (1/2 * 8) ^5 = 4^5
a wiec razem mamy -4^5 / 4^5 = - 1
^ oznacza do potegi
licznik=(-14)⁵:7⁵×2⁵=-2⁵×7⁵:7⁵×2⁵=-2¹⁰
mianownik:2⁻⁵:8⁻⁵=2⁻⁵:2⁻⁵×2⁻⁵×2⁻⁵=2⁻¹⁰
ułamek=-2¹⁰:2⁻¹⁰=-2⁰=-1
