R8 Persiapan UN 2017 diutamakan siswa - siswi SMP. harus pakai cara. \(^-^)/ (2^97.778 + 2^97.776) / (2^97.776 - 2^97.774) = .....

(2^97.778 + 2^97.776) / (2^97.776 - 2^97.774)
Pakai sifat distributif
= ( 2^97.774 ( 2^4 + 2^2) ) / ( 2^97.774 (2^2 - 1) ) <-- 2^97.774 keluar agar dpt dihilangkan
Coret 2^97.774 dr pembilang dn penyebut
Sisa :
= (2^4 + 2^2) / (2^2 - 1)
= (16 + 4) / (4 - 1)
= 20/3

≡ Ditanya: [tex]\frac{2^{97778}+2^{97776}}{2^{97776}-2^{97774}} [/tex]?

≡ Penyelesaian:
⇒ [tex]\frac{2^{97776}(2^{2}+1)}{2^{97776}(1-2^{-2})} [/tex]

⇒ [tex]\frac{(4+1)}{1-\frac{1}{4}}[/tex]

⇒ [tex]\frac{5}{\frac{3}{4}}=(5).(\frac{4}{3}) [/tex]

∴ [tex]\boxed{\frac{20}{3}}[/tex]
