Answer (1)
Jawaban:Ringkasan Pertanyaan: Sederhanakan ekspresi aljabar dan ubah ke bentuk pangkat positif. Solusi: 1. Soal 1:- x⁷y⁻⁵ / y⁶ = x⁷ / (y⁶ × y⁵) = x⁷ / y¹¹2. Soal 2:- (10a⁻⁷b¹¹) / (5a²b⁹) = (10/5) × (a⁻⁷ / a²) * (b¹¹ / b⁹)- = 2 × a^(-7-2) × b^(11-9)- = 2 × a⁻⁹ × b²- = 2b²/a⁹3. Soal 3:- (a⁵b⁻³c²) / (a³b⁴c) = (a⁵/a³) × (b⁻³/b⁴) × (c²/c)- = a^(5-3) × b^(-3-4) × c^(2-1)- = a² × b⁻⁷ × c- = a²c/b⁷ Jawaban: 1. x⁷ / y¹¹2. 2b²/a⁹3. a²c/b⁷
