Jika n (PxQ) = 18, n ( QxR ) = 24, n (R) = 4 hitunglah nilai n (P).​

Jawaban:

Pembahasan:

Diketahui n(P x Q) = 18, n(Q x R) = 24, dan n(R)=4

n(Q x R) = 24

→n(Q) x n(R) = 24

n(Q) x 4 = 24

⇒n(Q) = 24 =6

Kita ketahui bahwa:

n(P x Q) = 18

⇒n(P) x n(Q) = 18

⇒n(P) x6 =18

⇒n(P) = 18 == 6 3

Jadi, n(P) = 3.
