Ili kurahisisha usemi huu, tutaweka sawa denominator ya kila sehemu na kisha kuzijumlisha. Step 1: Rahisisha sehemu ya kwanza kwa kuondoa mizizi kwenye denominator. Tunazidisha namba na denominator kwa kiambishi cha 3+sqrt(5), ambacho ni 3-sqrt(5). (3)/(3+sqrt(5)) = (3)/(3+sqrt(5)) × 3-sqrt(5)3-sqrt(5) = 3(3-sqrt(5))3^2 - (sqrt(5))^2 = 9-3sqrt(5)9-5 = 9-3sqrt(5)4 Step 2: Rahisisha sehemu ya pili kwa kuondoa mizizi kwenye denominator. Tunazidisha namba na denominator kwa kiambishi cha 3-sqrt(5), ambacho ni 3+sqrt(5). 3sqrt(5)3-sqrt(5) = 3sqrt(5)3-sqrt(5) × 3+sqrt(5)3+sqrt(5) = 3sqrt(5)(3+sqrt(5))3^2 - (sqrt(5))^2 = 3sqrt(5) · 3 + 3sqrt(5) · sqrt(5)9-5 = 9sqrt(5) + 3 · 54 = 15+9sqrt(5)4 Step 3: Jumlisha sehemu zote mbili. Sasa tuna denominator sawa, tunaweza kujumlisha namba. 9-3sqrt(5)4 + 15+9sqrt(5)4 = (9-3sqrt(5)) + (15+9sqrt(5))4 = 9+15 - 3sqrt(5) + 9sqrt(5)4 = 24 + 6sqrt(5)4 Step 4: Rahisisha jibu la mwisho. Gawanya kila namba kwa 4. = (24)/(4) + 6sqrt(5)4 = 6 + 3sqrt(5)2 Jibu la mwisho ni: 6 + 3sqrt(5)2 Tuma swali linalofuata 📸
