Jawaban:Berikut langkah-langkah penyederhanaan: 1. Sederhanakan ekspresi dalam kurung:(yr²/pqr × pq²/yr²) = (yr² * pq²) / (pqr * yr²) = (p * q) / r (yr² disederhanakan)2. Substitusikan hasil ke dalam ekspresi utama:xy/pqr : (pq)/r = (xy/pqr) * (r/(pq)) = xy/(pqr) * (r/pq) = xy/(pq²r)3. Bentuk sederhana:xy/pq²r Jadi, bentuk sederhana dari xy/pqr : (yr²/pqr × pq²/yr²) adalah xy / (pq²r)
